Notes to the Condensed Consolidated Financial Statements

(unaudited)

Note 1. Overview and Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. These financial statements include the assets, liabilities, revenues and expenses of all subsidiaries and entities in which the Company has a controlling financial interest or is deemed to be the primary beneficiary. In determining whether the Company is the primary beneficiary of an entity, the Company applies a qualitative approach that determines whether it has both (i) the power to direct the economically significant activities of the entity and (ii) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. The Company uses the equity method to account for its investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions are eliminated from the accompanying condensed consolidated financial statements.

Nature of the Business

Fulgent Genetics, Inc., together with its subsidiaries and affiliated professional corporations (collectively referred to as the Company, unless otherwise noted or the context otherwise requires), is a technology-based company with a well-established clinical diagnostic business and a therapeutic development business. Its clinical diagnostic business offers molecular diagnostic testing services, comprehensive genetic testing, and high-quality anatomic pathology laboratory services designed to provide physicians and patients with clinically actionable diagnostic information to improve the quality of patient care. Its therapeutic development business is focused on developing drug candidates for treating a broad range of cancers using a novel nanoencapsulation and targeted therapy platform designed to improve the therapeutic window and pharmacokinetic profile of new and existing cancer drugs. The Company aims to transform from a genomic diagnostic business into a fully integrated precision medicine company.

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited consolidated financial statements as of and for the fiscal year ended December 31, 2022, which are included in the Company’s annual report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on February 28, 2023, or the 2022 Annual Report, and, in the opinion of management, include all adjustments, which are normal and recurring in nature, necessary for a fair presentation of the Company’s financial position and results of operations. Operating results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year or any other period. The accompanying Condensed Consolidated Balance Sheet as of December 31, 2022 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the disclosures required by U.S. GAAP. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements included in the 2022 Annual Report, including the notes thereto.

Note 2. Summary of Significant Accounting Policies

See the summary of the Company’s significant accounting policies set forth in the notes to its consolidated financial statements included in the 2022 Annual Report.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. These estimates, judgments and assumptions are based on historical data and experience available at the date of the accompanying condensed consolidated financial statements, as well as various other factors management believes to be reasonable under the circumstances. The Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from these estimates.

On an on-going basis, management evaluates its estimates, primarily those related to: (i) revenue recognition criteria, (ii) accounts receivable and allowances for credit losses, (iii) the useful lives of fixed assets and intangible assets, (iv) estimates of tax liabilities, (v) valuation of intangible assets and goodwill at time of acquisition and on a recurring basis, and (vi) valuation of investments.

Trade Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are stated at the amount the Company expects to collect. The Company maintains an allowance for credit losses for expected uncollectible trade accounts receivable, which is recorded as an offset to trade accounts receivable, and changes in allowance for credit losses are classified as a general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The Company assesses collectability by reviewing trade accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when it identifies specific customers that have deterioration in credit quality such that they may no longer share similar risk characteristics with the other receivables. In determining the amount of the allowance for credit losses, the Company uses a loss rate model or probability-of-default and loss given default model. Following the loss rate method, expected credit losses are determined based on an estimated historical loss rate. The probability of default method allows the ability to define a point of default and measure credit losses for receivables that have reached the point of default for purposes of calculating the allowance for credit losses. Loss given default represents the likelihood that a receivable that has reached the point of default will not be collected in full. The Company updates its loss rate and factors annually to incorporate the most recent historical data and adjusts the quantitative portion of the reserve through its qualitative reserve overlay. The Company looks at qualitative factors such as general economic conditions in determining expected credit losses. During the three and nine months ended September 30, 2023, the Company recorded an adjustment of $(2.3) million and $(4.3) million, respectively, in provision for credit losses for trade accounts receivable due to decreased allowance for uncollectible accounts. During the three and nine months ended September 30, 2022, the Company recorded $6.5 million and $25.3 million, respectively, of provision for credit losses for trade accounts receivable.

Redeemable Preferred Stock Investment

The redeemable preferred stock investment of $15.2 million as of September 30, 2023 represents the fair value of redeemable preferred stock of a private company that the Company purchased in July 2021. The investment is classified as available-for-sale debt securities. The fair value of available-for-sale debt security is included in the Condensed Consolidated Statement of Balance Sheets. Unrealized gain of $2.3 million and $2.8 million is excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2023, respectively, and unrealized loss of $748,000 and $10.7 million were excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2022, respectively. Since the Company intends on holding the preferred stock, and the preferred stock is not redeemable until July 2027, the investment is recorded as a long-term investment.

Foreign Currency Translation and Foreign Currency Transactions

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in accumulated other comprehensive income (loss) in the accompanying Condensed Consolidated Statements of Stockholders’ Equity. The Company and its subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, whereas reagents and supplies, property and nonmonetary assets and liabilities are measured at historical rates. Losses from these remeasurements were $230,000 and $2.0 million in the three and nine months ended September 30, 2023, respectively. Loss from these translations were $1.9 million and $3.7 million in the three and nine months ended September 30, 2022, respectively.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of net unrealized gain or loss on available-for-sale debt securities, net of tax, and foreign currency translation adjustments from the Company's subsidiaries not using the U.S. dollar as their functional currency. There were no reclassifications from other comprehensive income (loss) to net loss in the three and nine months ended September 30, 2023, and reclassification from other comprehensive income (loss) to net earnings was not significant in the three and nine months ended September 30, 2022. The tax effects related to net unrealized loss on available-for-sale debt securities were $1.2 million and $2.4 million in the three and nine months ended September 30, 2023, respectively. The tax effects related to net unrealized loss on available-for-sale debt securities were $3.6 million and $9.4 million in the three and nine months ended September 30, 2022, respectively.

Concentration of Customers

In certain periods, a small number of customers have accounted for a significant portion of the Company’s revenue. After aggregating customers that are under common control or affiliation, one customer contributed 14% and 11% of the Company's revenue for the three and nine months ended September 30, 2023, respectively. A different customer contributed 13% and 21% of the

8

Company's revenue for the three and nine months ended September 30, 2022, respectively. No customer comprised 10% or more of total accounts receivable as of September 30, 2023, and one customer comprised 17% of total accounts receivable as of December 31, 2022.

Disaggregation of Revenue

The Company classifies its customers into three payor types: (i) Insurance, including claim reimbursement from the U.S. Health Resources and Services Administration, or HRSA, for uninsured individuals, (ii) Institutional customers, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, or (iii) Patients who pay directly; as the Company believes these classifications best depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. The following table summarizes revenue from contracts with customers by payor type for the three and nine months ended September 30, 2023 and 2022.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
	(in thousands)
Testing Services by payor
Insurance	$	48,619	$	63,030	$	116,231	$	337,497
Institutional customers		35,164		42,280		100,238		212,980
Patients		904		345		2,239		787
Total Revenue	$	84,687	$	105,655	$	218,708	$	551,264

The insurance revenue category above includes zero and $92.7 million for the three and nine months ended September 30, 2022, respectively, for services related to claims covered by the HRSA COVID-19 Uninsured Program. The Company did not recognize any insurance revenue under HRSA COVID-19 Uninsurance Program for the three and nine months ended September 30, 2023.

$18.9 million variable consideration was recognized in the three months ended September 30, 2023 that related to COVID-19 tests completed in the prior periods due to the recent collection efforts, which was included as revenue from insurance in the table above. During the quarter ended September 30, 2023, the Company experienced a change in estimate related to variable consideration. This change resulted in a cumulative catch-up adjustment of $18.9 million. The Company estimates variable consideration using the expected value method. Any changes in variable consideration estimates that affect transactions are accounted for on a cumulative catch-up basis.

Contract Balances

Receivables from contracts with customers - Receivables from contracts with customers are included within trade accounts receivable on the Condensed Consolidated Balance Sheets. Net receivable from Insurance and Institutional customers represented 41% and 59%, respectively, as of September 30, 2023. Net receivable from Insurance and Institutional customers represented 14% and 86%, respectively, as of December 31, 2022.

Contracts assets and liabilities - Contract assets from contracts with customers associated with contract execution and certain costs to fulfill a contract are included in other current assets in the accompanying Condensed Consolidated Balance Sheets.

Note 4. Fair Value Measurements

The authoritative guidance on fair value measurements establishes a framework with respect to measuring assets and liabilities at fair value on a recurring basis and non-recurring basis. Under the framework, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as of the measurement date. The framework also establishes a three-tier hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability and are developed based on the best information available in the circumstances. The hierarchy consists of the following three levels:

Level 1:	Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
Level 2:	Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3:	Inputs are unobservable for the asset or liability.

11

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis, based on the above three-tier fair value hierarchy:

Total equity securities, debt securities and cash equivalents	$	833,206	$	97,253	$	708,568	$	27,385

The Company’s Level 1 assets include U.S. treasury bills and money market instruments and are valued based upon observable market prices. Level 2 assets consist of U.S. government and U.S. agency debt securities, municipal bonds, corporate debt securities and Yankee debt securities. Level 2 securities are valued based upon observable inputs that include reported trades, broker/dealer quotes, bids and offers. As of September 30, 2023, the Company had preferred stock of a privately held company, which was included in other long-term assets in the accompanying Condensed Consolidated Balance Sheets, and redeemable preferred stock of a private company that were measured using unobservable (Level 3) inputs. The fair value of redeemable preferred stock as of September 30, 2023 and December 31, 2022 was based on valuation performed by a third-party valuation company utilizing the guideline public company method under market approach and the discounted cash flow method under income approach. For the value of the investment in private equity securities, the Company elected to measure it at cost minus impairment, as the preferred stock of the privately held company did not have a readily determinable fair value, and no impairment loss was recorded as of September 30, 2023.

There were no transfers between fair value measurement levels during the three and nine months ended September 30, 2023 and 2022.

Operating Leases

See Note 9, Leases, for further information.

Purchase Obligations

The Company entered certain noncancelable purchase commitments with its vendors, which primarily consist of services, reagent and supplies, computer software, and medical lab equipment. As of September 30, 2023, the Company had non-cancelable purchase obligations of $51.1 million, of which $24.0 million is payable within twelve months, and the remainder, $27.1 million, is payable within the next five years.

Contingencies

From time to time, the Company may be subject to legal proceedings and claims arising in the ordinary course of business. In the opinion of management, the outcome of these matters would not have a material effect on the Company’s condensed consolidated financial position, results of operations or cash flows.

The Company has received a Civil Investigative Demand, or CID, issued by the U.S. Department of Justice pursuant to the False Claims Act related to its investigation of allegations of medically unnecessary laboratory testing, improper billing for laboratory testing, and remuneration received or provided in violation of the Anti-Kickback Statute and the Stark Law. Among other things, this CID requests information and records relating to certain of the Company’s customers named in the CID, which represent a small portion of the Company’s revenues. As disclosed in the Company’s prior filings, the U.S. Securities and Exchange Commission, or the SEC is also conducting a non-public formal investigation, which appears to relate to the matters raised in the CID requests and our Exchange Act reports filed for 2018 through 2020. The Company is fully cooperating with the U.S. Department of Justice and the SEC to promptly respond to the requests for information in this CID and investigation and does not presently expect this CID or resulting investigation or the SEC investigation to have a material adverse impact. However, the Company cannot predict when these matters will be resolved, the outcome of these matters, or their potential impact, which may ultimately be greater than what the Company currently expects.

Note 9. Leases

Lessee

The Company is a lessee to various non-cancelable operating leases with varying terms through April 2033 primarily for laboratory and office space and equipment.

Note 11. Income Taxes

The effective tax rate used for interim periods is the estimated annual effective consolidated tax rate, based on the current estimate of full year results, except that taxes related to specific events, if any, are recorded in the interim period in which they occur. The annual effective tax rate is based upon several significant estimates and judgments, including the estimated annual pre-tax income of the Company in each tax jurisdiction in which it operates, and the development of tax planning strategies during the year. In addition, the Company’s tax expense can be impacted by changes in tax rates or laws and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

The Company recorded consolidated provision for income taxes of $20.3 million and $12.0 million for the three and nine months ended September 30, 2023, respectively, compared with $414,000 and $51.5 million for the three and nine months ended September 30, 2022, respectively. The Company’s effective tax rate was 296% and (42%) for the three and nine months ended September 30, 2023, respectively, compared to 24% for both the three and nine months ended September 30, 2022. The change in the effective tax rate compared to prior periods is due to the establishment, in the current quarter, of a valuation allowance on the Company's net deferred tax assets.

The Company is under examination by certain tax authorities for the 2020 to 2021 tax years. While the timing of the conclusion of the examination is uncertain, the Company believes that adequate amounts have been reserved for adjustments that may result. During 2023, the statutes of limitations will lapse on the Company’s 2019 federal tax year and certain 2018 and 2019 state tax years. The Company does not believe the federal or state statute lapses or any other event will significantly impact the balance of unrecognized tax benefits in the next twelve months.

Interest and Other Income, net

Interest and other income, net, is primarily comprised of net interest income (expenses), which was $6.4 million and $1.5 million in the three months ended September 30, 2023 and 2022, respectively, and $15.2 million and $2.3 million in the nine months ended September 30, 2023 and 2022, respectively. This interest income (expense) related to interest earned on various investments in marketable securities including realized and holding gain (loss) on marketable equity securities, net of interest expenses incurred for our notes payable and margin loan. The increase is primarily due to increases in interest rates on investments relative to the prior comparative periods.

Provision for Income Taxes

Provision for income taxes was $20.3 million and $12.0 million for the three and nine months ended September 30, 2023, respectively, and $414,000 and $51.5 million for the three and nine months ended September 30, 2022, respectively. The effective tax rate was 296% and 24% for the three months ended September 30, 2023 and 2022, respectively. The effective tax rate was (42%) and 24% for the nine months ended September 30, 2023 and 2022, respectively. The change in the effective tax rate for the three and nine months ended September 30, 2023, relative to 2022, was due to the establishment, in the three months ended September 30, 2023, of a valuation allowance on the Company's net deferred tax assets. FASB ASC 740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred income tax assets will not be realized. The Company has evaluated the realizability of any of its deferred tax assets and has concluded that it is more likely than not that the Company may not realize benefit of its deferred tax assets, primarily as a result of operating losses in the nine months ended September 30, 2023, and, accordingly, has provided a full valuation allowance at September 30, 2023.

Net Loss Attributable to Noncontrolling Interest

Net loss attributable to noncontrolling interest represents net loss attributable to the minority shareholders from entities not wholly owned.

Liquidity and Capital Resources

Liquidity and Sources of Cash

We had $851.5 million and $852.9 million in cash, cash equivalents, and marketable securities as of September 30, 2023 and December 31, 2022, respectively. Our marketable securities primarily consist of U.S. government and U.S. agency debt securities, U.S. treasury bills, corporate bonds, municipal bonds, and Yankee debt securities as of September 30, 2023 and December 31, 2022.

Our primary uses of cash are to fund our operations and to fund strategic acquisitions as we continue to invest in and seek to grow our business. Cash used to fund operating expenses is impacted by the timing of our expense payments, as reflected in the changes in our outstanding accounts payable and accrued expenses.

We believe our existing cash, cash equivalent, and short-term marketable securities will be sufficient to meet our anticipated cash requirements for at least the next 12 months. Cash provided by operations significantly contributed to our ability to meet our liquidity needs, including paying for capital expenditures. However, cash provided by our operations fluctuates from period to period, which we expect may continue in the future. These fluctuations can occur because of a variety of factors, including, among others, factors relating to the demand for our tests, the amount and timing of sales, the prices we charge for our tests due to changes in product mix, customer mix, general price degradation for tests, or other factors, the rate and timing of our billing and collections cycles and the timing and amount of our commitments and other payments. Moreover, even if our liquidity expectations are correct, we may still seek to raise additional capital through securities offerings, credit facilities or other debt financings, asset sales or collaborations or licensing arrangements.

If we raise additional funds by issuing equity securities, our existing stockholders could experience substantial dilution. Additionally, any preferred stock we issue could provide for rights, preferences or privileges senior to those of our common stock, and our issuance of any additional equity securities, or the possibility of such an issuance, could cause the market price of our common stock to decline. The terms of any debt securities we issue or borrowings we incur, if available, could impose significant restrictions on our operations, such as limitations on our ability to incur additional debt or issue additional equity or other restrictions that could adversely affect our ability to conduct our business, and would result in increased fixed payment obligations. If we seek to sell assets or enter into collaborations or licensing arrangements to raise capital, we may be required to accept unfavorable terms or relinquish or license to a third party our rights to important or valuable technologies or tests we may otherwise seek to develop ourselves. Moreover, we may incur substantial costs in pursuing future capital, including investment banking, legal and accounting fees, printing and distribution expenses, and other similar costs. Additional funding may not be available to us when needed, on acceptable terms or at all. If we are not able to secure funding if and when needed and on reasonable terms, we may be forced to delay, reduce the scope

24

of, or eliminate one or more sales and marketing initiatives, research and development programs, or other growth plans or strategies. In addition, we may be forced to work with a partner on one or more aspects of our tests or market development programs, or initiatives, which could lower the economic value to us of these tests, programs or initiatives. Any such outcome could significantly harm our business, performance, and prospects.

Operating Activities

Cash provided by operating activities in the nine months ended September 30, 2023 was $12.1 million.

Financing Activities

Cash used in financing activities in the nine months ended September 30, 2023 was $21.8 million, which primarily related to $15.0 million repayment to the margin loan account, $2.4 million repayment to the notes payable, $2.2 million repurchase of common stock, and $1.6 million common stock withholding for employee tax obligations.

Cash used in financing activities in the nine months ended September 30, 2022 was $47.5 million, which primarily related to $45.3 million repurchase of common stock and $1.5 million related to common stock withholding for employee tax obligations.

For quantitative and qualitative disclosures about market risk, see Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our 2022 Annual Report.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. As required by Rule 13a-15(b) under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of September 30, 2023. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2023.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control (as required by Rule 13a-15(b) under the Exchange Act) over the financial reporting during the three months ended September 30, 2023 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

26

Inherent Limitations on Disclosure Controls and Procedures and Internal Control over Financial Reporting

Management recognizes that any controls and procedures, no matter how well-designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Because of these inherent limitations, our disclosure and internal controls may not prevent or detect all instances of fraud, misstatements or other control issues. In addition, projections of any evaluation of the effectiveness of disclosure or internal controls to future periods are subject to risks, including, among others, that controls may become inadequate because of changes in conditions or that the degree of compliance with policies or procedures may deteriorate.

27

EX-10.1

Exhibit 10.1

FULGENT GENETICS, INC.

AMENDED AND RESTATED INCENTIVE COMPENSATION RECOUPMENT POLICY

I.Introduction

The Compensation Committee of the Board of Directors (the “Committee”) of Fulgent Genetics, Inc. (the “Company”) believes it is in the best interests of the Company and its shareholders to create and maintain a culture that emphasizes integrity and accountability and that reinforces the Company’s pay-for-performance compensation philosophy. The Committee has therefore adopted this amended and restated policy, effective as of October 2, 2023 (the “Effective Date”), which provides for the recoupment of certain executive compensation in the event of (i) an accounting restatement resulting from material noncompliance with financial reporting requirements under the federal securities laws and (ii) serious misconduct (as discussed below in Section V(b)) (the “Policy”). This Policy is designed to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and final rules and amendments adopted by the Securities and Exchange Commission (the “SEC”) to implement the aforementioned legislation.

II.Administration

This Policy shall be administered by the Compensation Committee. The Committee shall recover any excess Financials Incentive-Based Compensation (as defined below) in accordance with this Policy unless such recovery would be impracticable, as determined by the Committee in accordance with Rule 10D-1 of the Exchange Act and any applicable rules or standards adopted by the SEC and the listing standards of any national securities exchange on which the Company’s securities are listed.

With respect to Incentive Compensation (as defined below) that is not also Financials Incentive-Based Compensation, the Committee will consider the facts and circumstances related to possible recoupment decisions and make determinations in its discretion regarding seeking recoupment. Any determination to seek recoupment under Section V(b) of this Policy shall only be made after providing the Covered Executive, upon their request, a reasonable opportunity to appear before the Committee to present their position regarding the alleged misconduct being considered by the Committee and to present and explain any exculpatory and/or mitigating information and related documents that they believe to be relevant. Any determinations made by the Committee shall be final and binding on all affected individuals.

III.Application of Policy

This Policy applies to the Company’s current and former executive officers, as determined by the Committee in accordance with the requirements of Section 10D of the Exchange Act and any applicable rules or standards adopted by the SEC and any national securities exchange on which the Company’s securities are listed, and such other employees who may from time to time be deemed subject to the Policy by the Committee (“Covered Executives”).

IV.Incentive-Based Compensation

a.Financials Incentive-Based Compensation

For purposes of this Policy, financials incentive-based compensation (“Financials Incentive-Based Compensation”) includes any compensation that is granted, earned, or vested based wholly or in part upon the attainment of any financial reporting measures that are determined and presented in accordance with the accounting principles (“GAAP Measures”) used in preparing the Company’s financial statements and any measures derived wholly or in part from such measures, as well as non-GAAP Measures, stock price, and total shareholder return (collectively, “Financial Reporting Measures”); however, it does not include: (i) base salaries; (ii) discretionary cash bonuses; (iii) awards (either cash or equity) that are based upon subjective, strategic, or operational standards, and (iv) equity awards that vest solely on the passage of time. Financials Incentive-Based Compensation is considered received in the fiscal period during

which the applicable reporting measure is attained, even if the payment or grant of such award occurs after the end of that period. If an award is subject to both time-based and performance-based vesting conditions, the award is considered received upon satisfaction of the performance-based conditions, even if such award continues to be subject to the time-based vesting conditions.

For the purposes of this Policy, Financials Incentive-Based Compensation may include, among other things, any of the following:

•Annual bonuses and other short- and long-term cash incentives.

•Stock options.

•Stock appreciation rights.

•Restricted stock or restricted stock units.

•Performance shares or performance units.

For purposes of this Policy, Financial Reporting Measures may include, among other things, any of the following:

•Company stock price.

•Total shareholder return.

•Revenues.

•Net income.

•Earnings before interest, taxes, depreciation, and amortization (EBITDA).

•Funds from operations.

•Liquidity measures such as working capital or operating cash flow.

•Return measures such as return on invested capital or return on assets.

•Earnings measures such as earnings per share.

b.Incentive Compensation

For purposes of this Policy, incentive compensation (“Incentive Compensation”) means (i) any equity or equity-based award granted on or after the Effective Date, and (ii) any cash-based performance or incentive award (i.e., bonus or cash incentive plan payment, including any amounts deferred with respect thereto) approved, awarded, or granted to a Covered Executive on or after the Effective Date, including Financials Incentive-Based Compensation.

V.Recoupment

a.Accounting Restatement

In the event the Company is required to prepare an accounting restatement of its financial statements due to the Company’s material noncompliance with any financial reporting requirement under U.S. securities laws, including any required accounting restatement to correct an error in previously issued financial statements that (i) is material to the previously issued financial statements or (ii) is not material to previously issued financial statements, but that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, the Committee will require reimbursement or forfeiture of any excess Financials Incentive-Based Compensation received by any Covered Executive during the three completed fiscal years immediately preceding the date on which the Company is required to prepare the accounting restatement (the “Look-Back Period”). For the purposes of this Policy, the date on which the Company is required to prepare an accounting restatement is the earlier of: (i) the date the Committee concludes or reasonably should have concluded that the Company is required to prepare a restatement to correct a material error, and (ii) the date a court, regulator, or other legally authorized body directs the Company to restate its previously issued financial statements to correct a material error.

2

Recovery of the Financials Incentive-Based Compensation is only required when the excess award is received by a Covered Executive (i) after the beginning of their service as a Covered Executive, (ii) who served as an executive officer at any time during the performance period for the Financials Incentive-Based Compensation, (iii) while the Company has a class of securities listed on a national securities exchange, and (iv) when that Covered Executive served in such covered position during the Lookback Period.

b.Serious Misconduct

On and after the Effective Date of this Policy, the Committee may seek recoupment of any (i) amounts under Incentive Compensation subject to recoupment under this Policy or (ii) any Incentive Compensation after the Effective Date, to the extent granted or awarded to or earned by a Covered Executive in respect of services as an employee, all as determined by the Committee (such amounts, “Recoverable Payment”), when in its judgment, after reviewing relevant facts and circumstances, it determines that: (a) a Covered Executive (i) engaged in serious misconduct, or (ii) failed to supervise a subordinate employee who engaged in serious misconduct which the Covered Executive knew, or was reckless in not knowing, was occurring, and (b) such misconduct resulted in a material violation of law or a written Company policy that caused significant financial or reputational harm to the Company. As used in this Policy, “serious misconduct” may be found to have occurred only where a Covered Executive or a supervised employee acted knowingly, intentionally, or recklessly in violating a law or written Company policy. For the avoidance of doubt, a Covered Executive’s business judgment made in good faith and in the reasonable belief that such judgments and related actions were in or not opposed to the best interests of the Company shall not subject the Covered Executive’s Incentive Compensation to recoupment.

VI.Excess Incentive Compensation: Amount Subject to Recovery

a.Accounting Restatement

The amount of Financials Incentive-Based Compensation subject to recovery is the amount the Covered Executive received in excess of the amount of Financials Incentive-Based Compensation that would have been paid to the Covered Executive had it been based on the restated financial statements, as determined by the Committee. The amount subject to recovery will be calculated on a pre-tax basis.

For Financials Incentive-Based Compensation received as cash awards, the erroneously awarded compensation is the difference between the amount of the cash award that was received (whether payable in a lump sum or over time) and the amount that should have been received applying the restated Financial Reporting Measure. For cash awards paid from bonus pools, the erroneously awarded Financials Incentive-Based Compensation is the pro rata portion of any deficiency that results from the aggregate bonus pool that is reduced based on applying the restated Financial Reporting Measure.

For Financials Incentive-Based Compensation received as equity awards that are still held at the time of recovery, the amount subject to recovery is the number of shares or other equity awards received or vested in excess of the number that should have been received or vested applying the restated financial reporting measure. If the equity award has been exercised, but the underlying shares have not been sold, the erroneously awarded compensation is the number of shares underlying the award.

In instances where the Company is not able to determine the amount of erroneously awarded Financials Incentive-Based Compensation directly from the information in the accounting restatement, the amount will be based on the Company’s reasonable estimate of the effect of the accounting restatement on the stock price or total shareholder return upon which the Financials Incentive-Based Compensation was received. In such instances, the Company will maintain documentation of the determination of that reasonable estimate.

b.Serious Misconduct

The determination by the Committee whether and the extent to which to seek recoupment of Incentive Compensation pursuant to Section V(b) of this Policy may be influenced by a variety of factors,

3

including, but not limited to: (i) the elements of the compensation received by the Covered Executive, (ii) retention, promotion, or succession planning considerations, (iii) pay equity factors, (iv) whether the underlying conduct was an isolated occurrence, (v) feasibility and cost of implementation, (vi) legal and compliance factors, (vii) whether other disciplinary actions have been taken against the Covered Executive, and (viii) the objective of administering the Policy in a way that does not discourage settlement of disputes when settlements are in the best long-term interests of the Company and its stockholders.

Based on the facts and circumstances, the Committee may decide on the appropriate recoupment method, including whether to seek recoupment of Recoverable Payments already paid or otherwise seek recoupment (totally or partially) of Recoverable Payments that have not vested or have not been paid. However, the Committee may not seek recoupment of any Recoverable Payments (a) following a change in control (as defined in the Covered Executive’s severance agreement) or (b) that were awarded more than three years prior to the first event giving rise to the recoupment. Recoupment determinations pursuant to this Policy shall only be made to the extent permitted by law, and this Policy shall be interpreted so as not to violate any law or regulation.

Fulgent Genetics, Inc.

Amended and Restated Executive Officer Incentive Plan

Effective October 30, 2023

Introduction

The Amended and Restated Executive Officer Incentive Plan (the “Plan”) is an annual incentive compensation program designed to support the pay for performance philosophy of Fulgent Genetics, Inc. (“Company”) by rewarding members of the executive management team for their contributions in the achievement of corporate profitability and other important performance targets. The Plan is intended to deliver competitive levels of incentive compensation at expected levels of corporate performance with substantial upside potential for superior performance. The Plan, as amended and restated, will apply to Performance Years beginning with the Performance Year ending December 31, 2023.

Purpose of the Plan

The purpose of the Plan is to:

▪Align the executive management team with the organization’s strategic plan and critical performance goals;

▪Motivate and reward the achievement of specific, measurable performance objectives;

▪Provide incentive payouts commensurate with the organization’s performance;

▪Provide competitive total compensation opportunities; and

▪Enable the organization to attract, motivate, and retain talent.

Participation and Eligibility

Participants in the Plan shall include the company’s executive officers as determined by the Administrator. Additional individuals may be added to or removed from the Plan as participants at the discretion of the Administrator. Eligibility in the Plan will be communicated to each participant in writing at the beginning of the Performance Year (as defined below).

Participants who join the organization during the Performance Year, or who transfer into an eligible position, and who are made eligible for the Plan in that year by the Administrator, will be eligible for a prorated incentive opportunity based on the number of full months the individual works in the eligible position. Generally, anyone joining the organization, or transferring into an eligible position, after September 30 will not be eligible for an incentive opportunity for that Performance Year.

Performance Period

The Plan will measure performance from January 1 to December 31 (“Performance Year”).

Target Incentive Opportunities

Each participant will have a specified annual target incentive opportunity based on their role. The target incentive will be expressed as a percentage of annual base salary for the Plan Year. The target incentive opportunities as a percent of annual base salary will be communicated to each participant in writing at the beginning of the Performance Year.

Performance Measures

The Plan delivers annual incentives based on company performance. The table below provides the performance metrics and weighting for each performance component.

Performance Metrics	Weightings
Revenue	50%
EBITDA	50%
Total	100%

At the beginning of the Performance Year, specific performance goals are defined and are approved by the Administrator. The goals reflect the strategic priorities for the Company. The Administrator may change the performance metrics and adjust the weightings for a Performance Year at any time in its sole discretion.

Determination of Incentive Awards

After the end of the Performance Year and completion of the financial statement audit, each participant will be eligible for an incentive award in the form of (i) cash or (ii) in the sole discretion of the Administrator (as defined below), either fully or partially in the form of fully vested restricted stock units (“RSUs”), to be issued pursuant to the Company’s Amended and Restated 2016 Omnibus Incentive Plan or other then-stockholder approved equity incentive plan, for a number of shares equal to the amount of the incentive award divided by the closing price of the Company’s common stock on the Payment Date (as defined below) (rounded up to the nearest whole share).

The value of the incentive award is calculated by taking (A) multiplied by (B), where:

(A)is the participant’s target incentive opportunity, and

(B)is the adjustment for company performance.

The Company performance is based on level of achievement of the goals. Threshold levels of performance are established for each goal. If the applicable threshold level of

Page 2

achievement is met, participants will be eligible to be awarded a pro rata portion of such goal’s target incentive based on the difference between the applicable threshold and the related goal. The maximum award is capped at 200% of the target incentive. Refer to the Appendix A for details relating to Plan funding and an illustration.

If threshold levels of performance are not met, then any incentive award will be at the discretion of the Administrator.

Incentive awards may be appropriately adjusted for all other extraordinary and unusual items or events as the Administrator determines may be necessary or appropriate in its sole and absolute discretion. The Administrator also retains the discretion to adjust individual participant awards up or down at any time based upon any other factors determined to be relevant, regardless of whether any of the performance metrics outlined herein are achieved.

Annual Incentive Timing and Payment

Following the end of the Performance Year, upon completion of the financial statement audit, the annual incentive award will be calculated for each participant and approved by the Administrator. Upon approval, incentive payments (less any applicable tax withholdings) shall be made to participants. Generally, payment will be made as soon as administratively possible; however, all payments made to participants under this Plan shall be paid on the date that is the earlier of (i) the second business day following the filing date of the Company’s Annual Report on Form 10-K for the applicable Performance Year or (ii) March 15 of the year following the Performance Year (the “Payment Date”).

Employees will only be eligible to earn an incentive award for the applicable Plan Year if the Employee remains employed until the payment date of the award. The incentive award shall not be deemed to be earned until the payment date, which is the date by which services by the Employee must be completed in order to effectuate earning such award. If a participant resigns or is terminated for any reason and subsequently violates the terms of a previously signed Confidentiality and Non-Solicitation Agreement or Employment Agreement, the participant shall also forfeit the right to retain any previous incentive award payments made and shall be required to repay the full amount of all prior incentive award payments paid, except as required by applicable law. Payments under this Plan are subject to the Company's Incentive Compensation Recoupment Policy as then in effect. If the Participant fails to repay any portion of the incentive amounts rightfully required to be returned, the Company may take legal action to recover any such amounts previously paid.

For a participant that was on an approved medical leave of absence or on a military leave of absence during the Performance Year, eligibility for an incentive award will be prorated based on the number of days worked in the Performance Year.

Although The Company does not guarantee the tax treatment of any payments under the Plan, the intent is that the payments under this Plan be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended, and all Treasury regulations and guidance.

About the Plan

The Board of Directors (the “Board”) will administer the Plan and may delegate the responsibility to administer the Plan to the Compensation Committee (“Administrator”). The Administrator shall have authority, duty, and power to interpret and construe the provisions of the Plan as it deems appropriate, to adopt, establish and revise rules, procedures and regulations relating to the Plan, to determine the conditions subject to which any benefits may be payable, to resolve all factual and legal questions concerning the status of the participants and others under the Plan, including but not limited to, eligibility for incentive awards, and to make any other determinations which it believes necessary or advisable for the administration of the Plan. Incentive awards payable are subject to approval by the Administrator. Incentive awards under this Plan will be payable only if the Administrator decides in its sole discretion that the employee is entitled to them under the Plan. The determinations, interpretations, and regulations of the Administrator and the calculations of the Administrator shall be final and binding on all persons and parties concerned.

No employee will have a claim as a matter of right to any incentive award until it is actually paid to him or her. The Company reserves the right to amend, modify, or terminate any or all the provisions of the Plan in the future in its sole discretion. This Plan does not constitute an agreement of any kind.

Impact on Benefits

Incentive payment received under this Plan may impact benefits. The benefit plans each define “compensation.” The definition may be different for each benefit plan. Refer to the benefit plan documents for additional information.

Employment at Will

While it is hoped that each participant’s employment relationship with the Company will be mutually rewarding and long-term, this document should not be construed as, and does not constitute, a contract of employment for any specific duration. The participant or Company may terminate the employment relationship at any time.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Overview and Basis of Presentation

Note 1. Overview and Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. These financial statements include the assets, liabilities, revenues and expenses of all subsidiaries and entities in which the Company has a controlling financial interest or is deemed to be the primary beneficiary. In determining whether the Company is the primary beneficiary of an entity, the Company applies a qualitative approach that determines whether it has both (i) the power to direct the economically significant activities of the entity and (ii) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. The Company uses the equity method to account for its investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions are eliminated from the accompanying condensed consolidated financial statements.

Nature of the Business

Fulgent Genetics, Inc., together with its subsidiaries and affiliated professional corporations (collectively referred to as the Company, unless otherwise noted or the context otherwise requires), is a technology-based company with a well-established clinical diagnostic business and a therapeutic development business. Its clinical diagnostic business offers molecular diagnostic testing services, comprehensive genetic testing, and high-quality anatomic pathology laboratory services designed to provide physicians and patients with clinically actionable diagnostic information to improve the quality of patient care. Its therapeutic development business is focused on developing drug candidates for treating a broad range of cancers using a novel nanoencapsulation and targeted therapy platform designed to improve the therapeutic window and pharmacokinetic profile of new and existing cancer drugs. The Company aims to transform from a genomic diagnostic business into a fully integrated precision medicine company.

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited consolidated financial statements as of and for the fiscal year ended December 31, 2022, which are included in the Company’s annual report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on February 28, 2023, or the 2022 Annual Report, and, in the opinion of management, include all adjustments, which are normal and recurring in nature, necessary for a fair presentation of the Company’s financial position and results of operations. Operating results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year or any other period. The accompanying Condensed Consolidated Balance Sheet as of December 31, 2022 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the disclosures required by U.S. GAAP. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements included in the 2022 Annual Report, including the notes thereto.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

See the summary of the Company’s significant accounting policies set forth in the notes to its consolidated financial statements included in the 2022 Annual Report.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. These estimates, judgments and assumptions are based on historical data and experience available at the date of the accompanying condensed consolidated financial statements, as well as various other factors management believes to be reasonable under the circumstances. The Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from these estimates.

On an on-going basis, management evaluates its estimates, primarily those related to: (i) revenue recognition criteria, (ii) accounts receivable and allowances for credit losses, (iii) the useful lives of fixed assets and intangible assets, (iv) estimates of tax liabilities, (v) valuation of intangible assets and goodwill at time of acquisition and on a recurring basis, and (vi) valuation of investments.

Trade Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are stated at the amount the Company expects to collect. The Company maintains an allowance for credit losses for expected uncollectible trade accounts receivable, which is recorded as an offset to trade accounts receivable, and changes in allowance for credit losses are classified as a general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The Company assesses collectability by reviewing trade accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when it identifies specific customers that have deterioration in credit quality such that they may no longer share similar risk characteristics with the other receivables. In determining the amount of the allowance for credit losses, the Company uses a loss rate model or probability-of-default and loss given default model. Following the loss rate method, expected credit losses are determined based on an estimated historical loss rate. The probability of default method allows the ability to define a point of default and measure credit losses for receivables that have reached the point of default for purposes of calculating the allowance for credit losses. Loss given default represents the likelihood that a receivable that has reached the point of default will not be collected in full. The Company updates its loss rate and factors annually to incorporate the most recent historical data and adjusts the quantitative portion of the reserve through its qualitative reserve overlay. The Company looks at qualitative factors such as general economic conditions in determining expected credit losses. During the three and nine months ended September 30, 2023, the Company recorded an adjustment of $(2.3) million and $(4.3) million, respectively, in provision for credit losses for trade accounts receivable due to decreased allowance for uncollectible accounts. During the three and nine months ended September 30, 2022, the Company recorded $6.5 million and $25.3 million, respectively, of provision for credit losses for trade accounts receivable.

Redeemable Preferred Stock Investment

The redeemable preferred stock investment of $15.2 million as of September 30, 2023 represents the fair value of redeemable preferred stock of a private company that the Company purchased in July 2021. The investment is classified as available-for-sale debt securities. The fair value of available-for-sale debt security is included in the Condensed Consolidated Statement of Balance Sheets. Unrealized gain of $2.3 million and $2.8 million is excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2023, respectively, and unrealized loss of $748,000 and $10.7 million were excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2022, respectively. Since the Company intends on holding the preferred stock, and the preferred stock is not redeemable until July 2027, the investment is recorded as a long-term investment.

Foreign Currency Translation and Foreign Currency Transactions

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in accumulated other comprehensive income (loss) in the accompanying Condensed Consolidated Statements of Stockholders’ Equity. The Company and its subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, whereas reagents and supplies, property and nonmonetary assets and liabilities are measured at historical rates. Losses from these remeasurements were $230,000 and $2.0 million in the three and nine months ended September 30, 2023, respectively. Loss from these translations were $1.9 million and $3.7 million in the three and nine months ended September 30, 2022, respectively.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of net unrealized gain or loss on available-for-sale debt securities, net of tax, and foreign currency translation adjustments from the Company's subsidiaries not using the U.S. dollar as their functional currency. There were no reclassifications from other comprehensive income (loss) to net loss in the three and nine months ended September 30, 2023, and reclassification from other comprehensive income (loss) to net earnings was not significant in the three and nine months ended September 30, 2022. The tax effects related to net unrealized loss on available-for-sale debt securities were $1.2 million and $2.4 million in the three and nine months ended September 30, 2023, respectively. The tax effects related to net unrealized loss on available-for-sale debt securities were $3.6 million and $9.4 million in the three and nine months ended September 30, 2022, respectively.

Concentration of Customers

In certain periods, a small number of customers have accounted for a significant portion of the Company’s revenue. After aggregating customers that are under common control or affiliation, one customer contributed 14% and 11% of the Company's revenue for the three and nine months ended September 30, 2023, respectively. A different customer contributed 13% and 21% of the

Company's revenue for the three and nine months ended September 30, 2022, respectively. No customer comprised 10% or more of total accounts receivable as of September 30, 2023, and one customer comprised 17% of total accounts receivable as of December 31, 2022.

Disaggregation of Revenue

The Company classifies its customers into three payor types: (i) Insurance, including claim reimbursement from the U.S. Health Resources and Services Administration, or HRSA, for uninsured individuals, (ii) Institutional customers, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, or (iii) Patients who pay directly; as the Company believes these classifications best depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. The following table summarizes revenue from contracts with customers by payor type for the three and nine months ended September 30, 2023 and 2022.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
	(in thousands)
Testing Services by payor
Insurance	$	48,619	$	63,030	$	116,231	$	337,497
Institutional customers		35,164		42,280		100,238		212,980
Patients		904		345		2,239		787
Total Revenue	$	84,687	$	105,655	$	218,708	$	551,264

The insurance revenue category above includes zero and $92.7 million for the three and nine months ended September 30, 2022, respectively, for services related to claims covered by the HRSA COVID-19 Uninsured Program. The Company did not recognize any insurance revenue under HRSA COVID-19 Uninsurance Program for the three and nine months ended September 30, 2023.

$18.9 million variable consideration was recognized in the three months ended September 30, 2023 that related to COVID-19 tests completed in the prior periods due to the recent collection efforts, which was included as revenue from insurance in the table above. During the quarter ended September 30, 2023, the Company experienced a change in estimate related to variable consideration. This change resulted in a cumulative catch-up adjustment of $18.9 million. The Company estimates variable consideration using the expected value method. Any changes in variable consideration estimates that affect transactions are accounted for on a cumulative catch-up basis.

Contract Balances

Receivables from contracts with customers - Receivables from contracts with customers are included within trade accounts receivable on the Condensed Consolidated Balance Sheets. Net receivable from Insurance and Institutional customers represented 41% and 59%, respectively, as of September 30, 2023. Net receivable from Insurance and Institutional customers represented 14% and 86%, respectively, as of December 31, 2022.

Contracts assets and liabilities - Contract assets from contracts with customers associated with contract execution and certain costs to fulfill a contract are included in other current assets in the accompanying Condensed Consolidated Balance Sheets. The Company did not have any contract assets as of September 30, 2023 and December 31, 2022. Contract liabilities are recorded when the Company receives payment prior to completing its obligation to transfer goods or services to a customer. Contract liabilities are included in the Condensed Consolidated Balance Sheets. Revenues of $731,000 and $8.5 million were recognized for the three months ended September 30, 2023 and 2022, respectively, and $2.2 million and $14.4 million were recognized for the nine months ended September 30, 2023 and 2022, respectively, related to contract liabilities at the beginning of the respective periods.

Customer Deposit

Customer deposit in the accompanying Condensed Consolidated Balance Sheets consists of payments received from customers in excess of their outstanding trade accounts receivable balances. These deposits will be offset against future testing receivables or refunded to the customers.

Recent Accounting Pronouncements

The Company evaluates all Accounting Standards Updates, or ASUs, issued by the Financial Accounting Standards Board, or FASB, for consideration of their applicability. ASUs not included in the Company’s disclosures were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s condensed consolidated financial statements.

Fair Value Measurements

Note 4. Fair Value Measurements

The authoritative guidance on fair value measurements establishes a framework with respect to measuring assets and liabilities at fair value on a recurring basis and non-recurring basis. Under the framework, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as of the measurement date. The framework also establishes a three-tier hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability and are developed based on the best information available in the circumstances. The hierarchy consists of the following three levels:

Level 1:	Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
Level 2:	Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3:	Inputs are unobservable for the asset or liability.

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis, based on the above three-tier fair value hierarchy:

The Company’s Level 1 assets include U.S. treasury bills and money market instruments and are valued based upon observable market prices. Level 2 assets consist of U.S. government and U.S. agency debt securities, municipal bonds, corporate debt securities and Yankee debt securities. Level 2 securities are valued based upon observable inputs that include reported trades, broker/dealer quotes, bids and offers. As of September 30, 2023, the Company had preferred stock of a privately held company, which was included in other long-term assets in the accompanying Condensed Consolidated Balance Sheets, and redeemable preferred stock of a private company that were measured using unobservable (Level 3) inputs. The fair value of redeemable preferred stock as of September 30, 2023 and December 31, 2022 was based on valuation performed by a third-party valuation company utilizing the guideline public company method under market approach and the discounted cash flow method under income approach. For the value of the investment in private equity securities, the Company elected to measure it at cost minus impairment, as the preferred stock of the privately held company did not have a readily determinable fair value, and no impairment loss was recorded as of September 30, 2023.

There were no transfers between fair value measurement levels during the three and nine months ended September 30, 2023 and 2022.

See Note 9, Leases, for further information.

Purchase Obligations

The Company entered certain noncancelable purchase commitments with its vendors, which primarily consist of services, reagent and supplies, computer software, and medical lab equipment. As of September 30, 2023, the Company had non-cancelable purchase obligations of $51.1 million, of which $24.0 million is payable within twelve months, and the remainder, $27.1 million, is payable within the next five years.

Contingencies

From time to time, the Company may be subject to legal proceedings and claims arising in the ordinary course of business. In the opinion of management, the outcome of these matters would not have a material effect on the Company’s condensed consolidated financial position, results of operations or cash flows.

The Company has received a Civil Investigative Demand, or CID, issued by the U.S. Department of Justice pursuant to the False Claims Act related to its investigation of allegations of medically unnecessary laboratory testing, improper billing for laboratory testing, and remuneration received or provided in violation of the Anti-Kickback Statute and the Stark Law. Among other things, this CID requests information and records relating to certain of the Company’s customers named in the CID, which represent a small portion of the Company’s revenues. As disclosed in the Company’s prior filings, the U.S. Securities and Exchange Commission, or the SEC is also conducting a non-public formal investigation, which appears to relate to the matters raised in the CID requests and our Exchange Act reports filed for 2018 through 2020. The Company is fully cooperating with the U.S. Department of Justice and the SEC to promptly respond to the requests for information in this CID and investigation and does not presently expect this CID or resulting investigation or the SEC investigation to have a material adverse impact. However, the Company cannot predict when these matters will be resolved, the outcome of these matters, or their potential impact, which may ultimately be greater than what the Company currently expects.

Income Taxes

Note 11. Income Taxes

The effective tax rate used for interim periods is the estimated annual effective consolidated tax rate, based on the current estimate of full year results, except that taxes related to specific events, if any, are recorded in the interim period in which they occur. The annual effective tax rate is based upon several significant estimates and judgments, including the estimated annual pre-tax income of the Company in each tax jurisdiction in which it operates, and the development of tax planning strategies during the year. In addition, the Company’s tax expense can be impacted by changes in tax rates or laws and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

The Company recorded consolidated provision for income taxes of $20.3 million and $12.0 million for the three and nine months ended September 30, 2023, respectively, compared with $414,000 and $51.5 million for the three and nine months ended September 30, 2022, respectively. The Company’s effective tax rate was 296% and (42%) for the three and nine months ended September 30, 2023, respectively, compared to 24% for both the three and nine months ended September 30, 2022. The change in the effective tax rate compared to prior periods is due to the establishment, in the current quarter, of a valuation allowance on the Company's net deferred tax assets.

The Company is under examination by certain tax authorities for the 2020 to 2021 tax years. While the timing of the conclusion of the examination is uncertain, the Company believes that adequate amounts have been reserved for adjustments that may result. During 2023, the statutes of limitations will lapse on the Company’s 2019 federal tax year and certain 2018 and 2019 state tax years. The Company does not believe the federal or state statute lapses or any other event will significantly impact the balance of unrecognized tax benefits in the next twelve months.

Acquisition-related intangibles included in the above tables are generally finite-lived and are carried at cost less accumulated amortization, except for In-Process Research and Development, or IPR&D, which is related to a business combination in 2022 and has an indefinite life until research and development efforts are completed or abandoned. All other finite-lived acquisition-related intangibles related to the business combinations in 2022 and 2021 are amortized on a straight-line basis over their estimated lives, which approximates the pattern in which the economic benefits of the intangible assets are expected to be realized.

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. These estimates, judgments and assumptions are based on historical data and experience available at the date of the accompanying condensed consolidated financial statements, as well as various other factors management believes to be reasonable under the circumstances. The Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from these estimates.

On an on-going basis, management evaluates its estimates, primarily those related to: (i) revenue recognition criteria, (ii) accounts receivable and allowances for credit losses, (iii) the useful lives of fixed assets and intangible assets, (iv) estimates of tax liabilities, (v) valuation of intangible assets and goodwill at time of acquisition and on a recurring basis, and (vi) valuation of investments.

Trade Accounts Receivable and Allowance for Credit Losses

Trade Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are stated at the amount the Company expects to collect. The Company maintains an allowance for credit losses for expected uncollectible trade accounts receivable, which is recorded as an offset to trade accounts receivable, and changes in allowance for credit losses are classified as a general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. The Company assesses collectability by reviewing trade accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when it identifies specific customers that have deterioration in credit quality such that they may no longer share similar risk characteristics with the other receivables. In determining the amount of the allowance for credit losses, the Company uses a loss rate model or probability-of-default and loss given default model. Following the loss rate method, expected credit losses are determined based on an estimated historical loss rate. The probability of default method allows the ability to define a point of default and measure credit losses for receivables that have reached the point of default for purposes of calculating the allowance for credit losses. Loss given default represents the likelihood that a receivable that has reached the point of default will not be collected in full. The Company updates its loss rate and factors annually to incorporate the most recent historical data and adjusts the quantitative portion of the reserve through its qualitative reserve overlay. The Company looks at qualitative factors such as general economic conditions in determining expected credit losses. During the three and nine months ended September 30, 2023, the Company recorded an adjustment of $(2.3) million and $(4.3) million, respectively, in provision for credit losses for trade accounts receivable due to decreased allowance for uncollectible accounts. During the three and nine months ended September 30, 2022, the Company recorded $6.5 million and $25.3 million, respectively, of provision for credit losses for trade accounts receivable.

Redeemable Preferred Stock Investment

Redeemable Preferred Stock Investment

The redeemable preferred stock investment of $15.2 million as of September 30, 2023 represents the fair value of redeemable preferred stock of a private company that the Company purchased in July 2021. The investment is classified as available-for-sale debt securities. The fair value of available-for-sale debt security is included in the Condensed Consolidated Statement of Balance Sheets. Unrealized gain of $2.3 million and $2.8 million is excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2023, respectively, and unrealized loss of $748,000 and $10.7 million were excluded from earnings and reported in other comprehensive income (loss) in the three and nine months ended September 30, 2022, respectively. Since the Company intends on holding the preferred stock, and the preferred stock is not redeemable until July 2027, the investment is recorded as a long-term investment.

Foreign Currency Translation and Foreign Currency Transactions

Foreign Currency Translation and Foreign Currency Transactions

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation included in accumulated other comprehensive income (loss) in the accompanying Condensed Consolidated Statements of Stockholders’ Equity. The Company and its subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, whereas reagents and supplies, property and nonmonetary assets and liabilities are measured at historical rates. Losses from these remeasurements were $230,000 and $2.0 million in the three and nine months ended September 30, 2023, respectively. Loss from these translations were $1.9 million and $3.7 million in the three and nine months ended September 30, 2022, respectively.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of net unrealized gain or loss on available-for-sale debt securities, net of tax, and foreign currency translation adjustments from the Company's subsidiaries not using the U.S. dollar as their functional currency. There were no reclassifications from other comprehensive income (loss) to net loss in the three and nine months ended September 30, 2023, and reclassification from other comprehensive income (loss) to net earnings was not significant in the three and nine months ended September 30, 2022. The tax effects related to net unrealized loss on available-for-sale debt securities were $1.2 million and $2.4 million in the three and nine months ended September 30, 2023, respectively. The tax effects related to net unrealized loss on available-for-sale debt securities were $3.6 million and $9.4 million in the three and nine months ended September 30, 2022, respectively.

Concentration of Customers

Concentration of Customers

In certain periods, a small number of customers have accounted for a significant portion of the Company’s revenue. After aggregating customers that are under common control or affiliation, one customer contributed 14% and 11% of the Company's revenue for the three and nine months ended September 30, 2023, respectively. A different customer contributed 13% and 21% of the

Company's revenue for the three and nine months ended September 30, 2022, respectively. No customer comprised 10% or more of total accounts receivable as of September 30, 2023, and one customer comprised 17% of total accounts receivable as of December 31, 2022.

Revenue from Contracts with Customers

Disaggregation of Revenue

The Company classifies its customers into three payor types: (i) Insurance, including claim reimbursement from the U.S. Health Resources and Services Administration, or HRSA, for uninsured individuals, (ii) Institutional customers, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, or (iii) Patients who pay directly; as the Company believes these classifications best depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. The following table summarizes revenue from contracts with customers by payor type for the three and nine months ended September 30, 2023 and 2022.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
	(in thousands)
Testing Services by payor
Insurance	$	48,619	$	63,030	$	116,231	$	337,497
Institutional customers		35,164		42,280		100,238		212,980
Patients		904		345		2,239		787
Total Revenue	$	84,687	$	105,655	$	218,708	$	551,264

The insurance revenue category above includes zero and $92.7 million for the three and nine months ended September 30, 2022, respectively, for services related to claims covered by the HRSA COVID-19 Uninsured Program. The Company did not recognize any insurance revenue under HRSA COVID-19 Uninsurance Program for the three and nine months ended September 30, 2023.

$18.9 million variable consideration was recognized in the three months ended September 30, 2023 that related to COVID-19 tests completed in the prior periods due to the recent collection efforts, which was included as revenue from insurance in the table above. During the quarter ended September 30, 2023, the Company experienced a change in estimate related to variable consideration. This change resulted in a cumulative catch-up adjustment of $18.9 million. The Company estimates variable consideration using the expected value method. Any changes in variable consideration estimates that affect transactions are accounted for on a cumulative catch-up basis.

Contract Balances

Receivables from contracts with customers - Receivables from contracts with customers are included within trade accounts receivable on the Condensed Consolidated Balance Sheets. Net receivable from Insurance and Institutional customers represented 41% and 59%, respectively, as of September 30, 2023. Net receivable from Insurance and Institutional customers represented 14% and 86%, respectively, as of December 31, 2022.

Contracts assets and liabilities - Contract assets from contracts with customers associated with contract execution and certain costs to fulfill a contract are included in other current assets in the accompanying Condensed Consolidated Balance Sheets. The Company did not have any contract assets as of September 30, 2023 and December 31, 2022. Contract liabilities are recorded when the Company receives payment prior to completing its obligation to transfer goods or services to a customer. Contract liabilities are included in the Condensed Consolidated Balance Sheets. Revenues of $731,000 and $8.5 million were recognized for the three months ended September 30, 2023 and 2022, respectively, and $2.2 million and $14.4 million were recognized for the nine months ended September 30, 2023 and 2022, respectively, related to contract liabilities at the beginning of the respective periods.

Customer Deposit
