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, 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, or PCs (collectively referred to as the Company, unless otherwise noted or the context otherwise requires), is a technology-based company with a well-established laboratory services business and a therapeutic development business. Its laboratory services business includes technical laboratory services and testing services and professional interpretation of laboratory results by licensed physicians. 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, 2024, 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, 2025, or the 2024 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, 2024, 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 2024 Annual Report, including the notes thereto.

Note 2. Summary of Significant Accounting Policies

See Note 2, Summary of Significant Accounting Policies, to the Company’s Consolidated Financial Statements included in the 2024 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 ongoing 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 goodwill and indefinite-lived intangible assets 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.

A roll-forward of the activity in the Company’s allowance for credit losses for the six months ended June 30, 2025, dollars in thousands, is as follows:


Allowance for credit losses at beginning of year	$	20,458
Current period provision		4,666
Write-downs		(4,326	)
Recoveries of amounts previously charged off		618
Allowance for credit losses as of June 30, 2025	$	21,416

Finite-Lived Intangible Assets

Intangible assets, unless determined to be indefinite-lived, are amortized over their estimated useful lives. The Company amortizes intangible assets on a straight-line basis with definite lives generally over periods ranging from three to 14 years. See Note 14, Goodwill and Intangible Assets, for details of intangible assets.

Impairment of Long-Lived Assets

The Company evaluates the carrying amount of its long-lived assets whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset and its eventual disposition are less than the carrying amount of the asset.

Goodwill and Indefinite-Lived Intangibles

In-process research & development, or IPR&D, costs are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts. If and when development is complete, the associated assets would be deemed finite-lived and would then be amortized based on their respective estimated useful lives at that point in time.

The Company assesses goodwill and indefinite-lived intangibles for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company may choose to bypass a qualitative assessment of impairment for any reporting unit and proceed directly to performing a quantitative assessment. An impairment loss would be recognized for the amount by which the reporting unit’s carrying amount exceeds its fair value.

The Company’s quantitative assessment includes estimating the fair value of each reporting unit and comparing it to its carrying value. The Company estimates the fair value of reporting units using both income-based and market-based valuation methods and typically engages a third-party appraisal firm to assist with the valuation. The estimated fair value for each reporting unit is determined based upon the range of estimated values developed from the income and market-based methods. If the estimated fair value of a reporting unit exceeds its carrying value, the goodwill is not impaired, and no further review is required.

The income-based fair value methodology is based on a reporting unit’s forecasted future cash flows that are discounted to the present value using the reporting unit’s weighted-average cost of capital. Under the income-based approach, it requires management’s assumptions and judgments regarding economic conditions in the markets in which the company operates and conditions in the capital markets, many of which are outside of management’s control. The market-based fair value methodology looks at the guideline public

company valuation method to determine the prices of comparable public companies and looks at merger and acquisition methods, similar businesses that were sold recently, to estimate the value of the reporting units. Under the market-based approach, judgment is required in evaluating market multiples and recent transactions.

Fair Value of Financial Instruments

The Company’s financial instruments consist principally of cash and cash equivalents, marketable securities, trade accounts receivable, restricted cash, a redeemable preferred stock investment, preferred stock investments, accounts payable, and accrued liabilities. The carrying amounts of certain of these financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short maturities. Fair value of marketable securities, the redeemable preferred stock investment, and the preferred stock investments is disclosed in Note 4, Fair Value Measurements, to the accompanying condensed consolidated financial statements.

Concentrations of Credit Risk, Customers, and Suppliers

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, trade accounts receivable, and marketable securities. As of June 30, 2025, substantially all of the Company’s cash and cash equivalents were deposited in accounts at financial institutions, and amounts typically exceed federally insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial strength of the depository institutions in which its cash and cash equivalents are held.

In certain periods, a small number of customers has accounted for a significant portion of the Company’s revenue. For the laboratory services segment, aggregating customers under common control, one customer comprised of $17.6 million, or 22%, of total revenue in the three months ended June 30, 2025, and $35.2 million, or 23%, of the Company’s revenue in the six months ended June 30, 2025. The same customer comprised of $16.9 million, or 24%, of total revenue in the three months ended June 30, 2024, and $29.6 million, or 22%, of the Company’s revenue in the six months ended June 30, 2024. The same customer comprised 29% of total accounts receivable, net, as of June 30, 2025, and 15% of total accounts receivable, net, as of December 31, 2024. For the therapeutic development segment, the Company does not have customers or revenue as it does not have any commercialized or approved drug candidates.

The Company’s therapeutic development business relies on ANP Technologies, Inc., or ANP, for certain laboratory services, equipment, tools, and drug intermediates in connection with research and development efforts. In July 2025, the Company completed an acquisition of 100% of ANP. See more details in Note 17. Subsequent Events. The Company also relies on a limited number of suppliers for certain laboratory substances used in the chemical reactions incorporated into its processes, referred to as reagents, as well as for the sequencers and various other equipment and materials it uses in its laboratory operations. In particular, the Company relies on a sole supplier for the next generation sequencers and associated reagents it uses to perform its genetic tests and as the sole provider of maintenance and repair services for these sequencers. The Company’s laboratory operations would be interrupted if it encountered delays or difficulties securing these reagents, sequencers, other equipment or materials or maintenance and repair services, which could occur for a variety of reasons, including if the Company needs a replacement or temporary substitute for any of its limited or sole suppliers and is not able to locate and make arrangements with an acceptable replacement or temporary substitute. The Company’s development efforts could also be delayed or interrupted if it is unable to procure items needed for its therapeutic development activities. The Company believes there are currently only a few other manufacturers that are capable of supplying and servicing some of the equipment and other materials necessary for its laboratory operations, including sequencers and various associated reagents.

Reportable segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker, in making decisions regarding resource allocation and assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company reports its business in two segments, a laboratory services business and a therapeutic development business. For further financial information about these segments, including information for each of the periods presented regarding revenue, operating income (loss), and other important information, see Note 7, Reportable Segment and Geographic Information, to the accompanying condensed consolidated financial statements.

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 gain (loss) included in the accompanying Condensed Consolidated Statements of Comprehensive Loss.

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, and reagents and supplies, property, and nonmonetary assets and liabilities at historical rates. Gains and losses from these measurements are included in other income, net, in the accompanying Condensed Consolidated Statements of Operations. Gains and losses from foreign currency exchange were not significant for the three and six months ended June 30, 2025, and 2024.

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 (loss) 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.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive income or loss. Other comprehensive income or 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 was no reclassification from other comprehensive income or loss to net loss in the three and six months ended June 30, 2025. Reclassifications from other comprehensive loss to net loss were $0.3 million and $0.9 million in the three and six months ended June 30, 2024, respectively. The tax effect related to net unrealized gain or loss on the available-for-sale debt securities was zero in each of the three and six months ended June 30, 2025, and 2024, due to the valuation allowance that precludes the Company from recognizing the deferred tax benefit.

Disaggregation of Revenue

The Company classifies its customers into three payor types: (i) Institutional, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, (ii) Insurance, or (iii) Patients who pay directly, as the Company believes this best depicts 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 six months ended June 30, 2025, and 2024:


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
	(in thousands)
Revenue by payor
Institutional	$	45,619	$	38,950	$	86,943	$	72,554
Insurance		34,385		31,100		65,129		61,143
Patients		1,799		978		3,194		1,816
Total revenue	$	81,803	$	71,028	$	155,266	$	135,513

During the three and six months ended June 30, 2024, the Company experienced a change in estimate related to variable consideration, leading to the recognition of $0.6 million and $1.8 million variable consideration, respectively, that related to COVID-19 test services completed in the prior periods due to collection efforts. This was included as revenue from insurance in the table above. There was zero such variable consideration recognized in each of the three and six months ended June 30, 2025. 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. Receivables from Insurance and Institutional customers represented 38% and 62%, respectively, as of June 30, 2025, and 44% and 56%, respectively, as of December 31, 2024.

Contract 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. 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 $0.3 million and $0.2 million were recognized for the three and six months ended June 30, 2025, respectively, and $0.4 million and $1.2 million were recognized for the three and six months ended June 30, 2024, respectively, related to contract liabilities at the beginning of the respective periods.

Prior Period Reclassifications

Certain amounts reported in the prior period have been reclassified to conform with the current period presentation. In the Condensed Consolidated Statements of Cash Flow, the Company has separated income taxes from its previous inclusion in other current and long-term assets. In the Condensed Consolidated Statements of Operations, the Company has also separated interest income, and interest expenses from its previous inclusion in other income (expense), net. In Note 6. Other Significant Balance Sheet Accounts, the Company has combined accrued legal liabilities with other accrued liabilities.

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.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures. This update requires more detailed information on certain income tax disclosures including the income tax rate reconciliation and income taxes paid. Amendments in this update are effective for annual periods beginning December 15, 2024, for public entities, and early adoption is permitted. This update is intended to result in enhanced income tax disclosures, and the Company does not expect any impact to income tax expense.

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This update requires disclosure in the notes to financial statements of specified information about certain costs and expenses. Amendments in this update are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impacts of this amendment on its consolidated financial statements and related disclosure.

The Company does not expect that any other recently issued accounting guidance will have a significant effect on its condensed consolidated financial statements.

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 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 June 30, 2025, and December 31, 2024, the Company had preferred stock of two privately-held companies, which were included in other long-term assets in the accompanying Condensed Consolidated Balance Sheets, that were measured using unobservable (Level 3) inputs. For the value of the investment in private equity securities, the Company elected to measure them at cost minus impairment, as the preferred stock of the privately-held companies did not have a readily determinable fair value.

During the three and six months ended June 30, 2025, the Company performed a qualitative assessment to determine if any of its equity investments measured at cost minus impairment were impaired. Indicators considered included significant declines in the investee’s operating performance, adverse changes in industry conditions, and deterioration in the investee’s financial condition. As part of this review, the Company identified that Helio Genomics, Inc., or Helio Genomics, an investee in which the Company holds a non-marketable equity investment, exhibited several adverse conditions, including a deterioration in financial condition and the inability to secure sufficient financing to support future operations. Given these developments and their impact on Helio Genomics’ ability to continue funding its operations, management concluded that the Company’s investment in Helio Genomics was impaired. To estimate the fair value of the investment, the Company employed a discounted cash flow analysis, using assumptions including projected revenues and expenses, discount rates, and a terminal value multiple. The resulting estimated fair value was deemed insignificant.

The carrying amount of the investment was $9.9 million. Accordingly, the Company recognized an impairment loss of $9.9 million. The impairment is reflected in “Other Expenses” within the Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2025. The carrying amount of the investment in Helio Genomics on the Condensed Consolidated Balance Sheet was reduced to its fair value of an insignificant amount, which now represents its new cost basis. In accordance with Accounting Standards Codification 321, no subsequent increases in the fair value will be recognized in net income for this investment.

The Company continues to monitor its investments for changes in facts and circumstances that may indicate further impairments or observable price changes in orderly transactions.

There was no impairment loss recorded as of June 30, 2025 for the other preferred stock investment.

There were no transfers between fair value measurement levels during the three and six months ended June 30, 2025, and 2024.

Note 7. Reportable Segment and Geographic Information

The Company has two distinct reportable segments. The laboratory services operating segment offers technical laboratory and testing services and professional interpretation of laboratory results by licensed physicians who specialize in pathology and oncology. The therapeutic development operating segment is a pharmaceutical research and development entity.

The Company’s Chief Executive Officer serves as its Chief Operating Decision Maker, or CODM. The CODM oversees the Company’s operations and evaluates financial data for its two operating segments separately to make resource allocation decisions. The financial information regularly provided to the CODM includes various performance metrics by reportable segment, such as gross profit, operating income or loss, income or loss before income taxes, net income or loss from consolidated operations, and net income or loss attributable to Fulgent, all presented in accordance with U.S. GAAP. Additionally, the CODM receives these metrics on a non-GAAP basis, which excludes the impact of equity-based compensation expenses, goodwill impairment losses, amortization of intangible assets, and restructuring costs, if applicable. Although multiple financial metrics are provided, the CODM primarily relies on adjusted operating income or loss, on a non-GAAP basis, to evaluate segment performance and allocate resources as this measure enhances the CODM's ability to compare past financial performance with current performance and analyze underlying business performance and trends. The balance sheet is presented on a consolidated basis, as the CODM does not use asset or liability information, including fixed assets, to assess segment performance. As a result, segment asset and liability details are not disclosed. The non-GAAP financial measures disclosed below should not be considered a substitute for, or superior to, financial measures determined or calculated in accordance with GAAP.

There is no inter-segment allocation of interest expense and income taxes. There is no inter-segment revenue and operating income or loss. The Company did not allocate income tax by segment. Information regarding the Company’s operations and assets for its reportable segments as well as geographic information are as follows, all dollars are in thousands:

Note 8. Debt, Commitments, and Contingencies

Debt

Notes payable as of June 30, 2025, consisted of $2.4 million of notes payable related to an installment sale contract the Company entered in February 2022 for a building. The notes payable related to the installment sale are due in February 2030, and carry an interest rate of 1.08%. The current portion and noncurrent portion are $0.5 million and $2.0 million, respectively, and the noncurrent portion is included in the other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets. The interest expenses for the three and six months ended June 30, 2025, and 2024, were not significant.

Operating and Finance Leases

See Note 9, Leases, for further information.

Contingencies

From time to time, the Company may be subject to legal proceedings and claims arising in the ordinary course of business.

As previously disclosed in the Company’s periodic reports filed pursuant to the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Company has received a Civil Investigative Demand, or CID, issued by the U.S. Department of Justice, or the DOJ, 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 this CID.

Similar to other laboratories in the industry, the Company has been subject to an audit by the U.S. Health Resources and Services Administration, or HRSA, with respect to its reimbursement for COVID-19 tests furnished to patients believed to be uninsured. The Company recorded approximately $548.9 million of reimbursements from HRSA under the Uninsured Program during the years ended December 31, 2022, 2021, and 2020. There is uncertainty with respect to the methodology HRSA will use in its audit and whether and how HRSA will extrapolate audit results. The Company has provided HRSA’s auditors with requested information in

connection with its audit in an effort to resolve any issues related to its audit, including any reimbursed amounts that may need to be returned to HRSA. The Company has also received a CID issued by the DOJ pursuant to the False Claims Act related to the DOJ’s investigation as to whether the Company submitted or caused to be submitted false claims to the Uninsured Program.

The Company is fully cooperating with the DOJ in connection with the CIDs that it has received. The Company cannot currently predict when these CIDs and HRSA audit matters will be resolved, the reasonable or likely outcome of these matters, or their potential impact, which may materially and adversely affect the Company’s business, prospects, and financial condition. These matters are not formal claims, and discussions and investigations remain ongoing. As such, the Company cannot reasonably estimate the loss or range of loss, if any, that may result from any material government investigations, audits, and reviews in which it is currently involved, given the inherent difficulty in predicting regulatory action, fines and penalties, if any, and the various remedies and levels of judicial review available to the Company in the event of an adverse finding. As a result, the Company has not recorded any liability related to these CIDs or audit matters.

In addition, and as previously disclosed, the SEC was conducting a non-public formal investigation, which related to (i) the matters raised in the requests for the CID regarding 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 and (ii) the Company’s Exchange Act reports filed for 2018 through 2020. On May 6, 2024, the SEC staff advised the Company that the SEC staff made a preliminary determination to recommend that the SEC file an enforcement action against the Company based on a corporate negligence theory, which, if authorized, would have alleged violations of the Exchange Act. In April 2025, the SEC advised the Company that it had concluded this investigation, with no enforcement action recommended. The Company previously recorded a $1.0 million potential liability with respect to this matter and is no longer recording any potential liability in connection with this matter.

Note 9. Leases

Lessee

The Company is party as a lessee to various non-cancelable operating leases with varying terms through March 2034 primarily for laboratory and office space and equipment. The Company has options to renew some of these leases after their expirations. On a lease-by-lease basis, the Company considers such options, which may be elected at the Company’s sole discretion, in determining the lease term. The Company also has various finance leases for lab equipment with varying terms through December 2026, of which some were acquired in business combinations. The Company does not have any leases with variable lease payments. The Company’s operating lease agreements do not contain any residual value guarantees, material restrictive covenants, bargain purchase options, or asset retirement obligations.

The Company’s headquarters are located in El Monte, California, which is comprised of various corporate offices and a laboratory certified under the Clinical Laboratory Improvement Amendments of 1988, or CLIA, accredited by the College of American Pathologists, or CAP, and licensed by the State of California Department of Public Health. Other CLIA-certified laboratories are located in Coppell, Texas; Needham, Massachusetts; Phoenix, Arizona; and Alpharetta, Georgia. The Company is also in the process of obtaining NATA accreditation in Dulwich, Australia.

The operating and finance lease right-of-use asset, short-term lease liabilities, and long-term lease liabilities as of June 30, 2025, and December 31, 2024, were as follows:

Total	$	10,039	$	11,635	$	20,589	$	23,153

Note 11. Income Taxes

The Company recorded consolidated benefit from income taxes of $2.3 million and $2.1 million for the three and six months ended June 30, 2025, respectively, compared to $2.1 million and $2.5 million for the three and six months ended June 30, 2024, respectively. The Company’s effective tax rates were 11% and 6% for the three and six months ended June 30, 2025, respectively, compared to 19% and 10% for the three and six months ended June 30, 2024, respectively. The change in the effective tax rate compared to prior periods is due to the valuation allowance that precludes the Company from recognizing the benefit from net operating losses.

The Company is under examination by certain tax authorities for the 2020 to 2021 and 2023 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 2025, the statutes of limitations will lapse on the Company’s 2021 federal tax year and certain 2020 and 2021 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 12 months.

The Company received an insignificant amount and $1.7 million in income tax refunds in the three and six months ended June 30, 2025, respectively, and $0.7 million and $7.0 million in the three and six months ended June 30, 2024, respectively. The income tax refunds received were not netted in the income tax paid amounts included in the supplemental disclosure in the accompanying Condensed Consolidated Statements of Cash Flows.

During the three months ended June 30, 2025, the Company purchased $33.8 million of Investment Tax Credits under the transferability provisions of the Inflation Reduction Act of 2022 for $31.7 million in cash. The $2.1 million difference between the purchase price and the face value of the credits has been recorded as an increase to the Company’s income tax benefit for the period. The Company will not utilize any of the acquired credits on its 2024 tax return. Instead, the Company will carry back the credits to its 2021 tax year and file a request for a refund. As such, the entire $33.8 million is reflected as an increase in the Company’s prepaid income tax in other current assets in the accompanying Condensed Consolidated Balance Sheets as of June 30, 2025.

Note 12. Loss per Share

The following table presents the calculation of basic and diluted loss per share for the three and six months ended June 30, 2025, and 2024:


	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
	(in thousands)
Net loss attributable to Fulgent	$	(18,957	)	$	(8,710	)	$	(30,487	)	$	(22,172	)

Weighted-average common shares - outstanding, basic		30,544			30,098			30,687			29,933
Weighted-average common shares - outstanding, diluted		30,544			30,098			30,687			29,933

Loss per share:

Diluted	$	(0.62	)	$	(0.29	)	$	(0.99	)	$	(0.74	)

The following securities have been excluded from the calculation of diluted loss per share because their effect would have been anti-dilutive:


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
	(in thousands)
Stock options		101		228		101		228
Restricted stock units		2,187		2,057		2,187		2,057

In the three and six months ended June 30, 2025, and 2024, the Company had outstanding stock options and restricted stock units that were excluded from the weighted-average share calculation for continuing operations due to the Company’s net loss positions.

Note 13. Related Party

Ming Hsieh, the Chief Executive Officer and Chairperson of the Board of Directors, was on the board of directors and an approximately 20% owner of ANP prior to April 25, 2025, with which the Company entered into certain drug-related licensing and development service agreements. The Chief Executive Officer of Fulgent Pharma, Ray Yin, is the Founder, President and Chief Technology Officer of ANP. The Company incurred $0.1 million and $0.6 million related to the licensing and development services in the three and six months ended June 30, 2025, prior to April 25, 2025, respectively, and $0.3 million and $1.0 million in the three and six months ended June 30, 2024, respectively. As of April 25, 2025, and December 31, 2024, the Company owed $0.3 million and $0.2 million, respectively, to ANP in connection with these relationships. The Company also entered into an employee service agreement with ANP in April 2023 and recognized insignificant amounts in the three and six months ended June 30, 2025, and 2024. Insignificant amounts were owed to the Company by ANP in connection with the employee service agreement as of April 25, 2025, and December 31, 2024. In July 2025, the Company completed an acquisition of 100% of ANP. See more details in Note 17. Subsequent Events.

Note 14. Goodwill and Intangible Assets

There was no change in the carrying amount in the six months ended June 30, 2025. Goodwill as of June 30, 2025, and December 31, 2024, was $22.1 million, all of which was related to the therapeutic development business.

The Company has identified its laboratory services business and its therapeutic development business as its two operating segments, and the Company determined that the operating segments represented the two reporting units.

The Company tests for goodwill impairment at the reporting unit level on December 31st of each year and more frequently if events or circumstances indicate a potential impairment.

Therapeutic Development

Based upon the results of the quantitative assessments the Company performed as of December 31, 2024, the Company concluded that the fair values of the therapeutic development reporting unit and the IPR&D asset at December 31, 2024, were greater than the carrying values and that there was no impairment. There have been no significant changes in the six months ended June 30, 2025.

There can be no assurance that the estimates and assumptions management made for the purposes of the goodwill or IPR&D impairment analysis will prove to be accurate predictions of future performance. It is possible that the conclusions regarding impairment or recoverability of goodwill or intangible assets could change in future periods. Management will continue to monitor the therapeutic development reporting unit. For all IPR&D projects, there are major risks and uncertainties associated with the timely and successful completion of development and commercialization of these drug candidates, including the ability to confirm their efficacy based on data from clinical trials, the ability to obtain necessary regulatory approvals, and the ability to successfully complete these tasks within budgeted costs. The Company is not able to market a human therapeutic without obtaining regulatory approvals, and such approvals require completing clinical trials that demonstrate a drug candidate is safe and effective. In addition, the availability and extent of coverage and reimbursement from insurance payors, including government healthcare programs and private insurance plans, impact the revenues a product can generate. Consequently, the eventual realized value, if any, of these acquired IPR&D projects may vary from their estimated fair values.

Summaries of intangible assets balances as of June 30, 2025, and December 31, 2024, were as follows:


	Weighted-Average Amortization Period	June 30, 2025			December 31, 2024

Total			64,590			64,590
Total intangible assets, net		$	131,060		$	134,978

Acquisition-related intangibles included in the above tables are generally finite-lived and are carried at cost less accumulated amortization, except for IPR&D, which is related to the acquisition of Fulgent Pharma 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 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.

Amortization of intangible assets was $2.0 million and $4.0 million in each of the three and six months ended June 30, 2025, and 2024, respectively.

Based on the carrying value of intangible assets recorded as of June 30, 2025, and assuming no subsequent impairment of the underlying assets, the annual amortization expense for intangible assets is expected to be as follows:


	Amounts
	(in thousands)
Year ending December 31,
2025 (remaining 6 months)	$	3,985
2026		7,665
2027		7,205

2029		6,913
2030		6,785
Thereafter		26,747
Total	$	66,470

Note 15. Stock Repurchase Program

In March 2022, the Company’s Board of Directors authorized a $250.0 million stock repurchase program. Under the stock repurchase program, the Company may repurchase shares from time to time in the open market or in privately negotiated transactions. The stock repurchase program has no expiration from the date of authorization.

During the three and six months ended June 30, 2025, the Company repurchased 0.2 million and 0.6 million shares of its common stock, respectively, at an aggregate cost of $3.0 million and $10.9 million, respectively, under the stock repurchase program. During the three and six months ended June 30, 2024, the Company repurchased zero and 10,000 shares of its common stock, respectively, at an aggregate cost of zero and $0.2 million, respectively. As of June 30, 2025, a total of approximately $139.6 million remained available for future repurchases of its common stock under the stock repurchase program.

Note 16. Retirement Plans

The Company offers a 401(k) retirement savings plan, or the 401(k) Plan, for its employees, including its executive officers, who satisfy certain eligibility requirements. The Internal Revenue Code of 1986, as amended, allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) Plan. The Company matches contributions to the 401(k) Plan based on the amount of salary deferral contributions the participant makes to the 401(k) Plan. The Company will match up to 4% of an employee’s compensation that the employee contributes to their 401(k) Plan account. Total Company matching contributions to the 401(k) Plan were $1.0 million and $2.2 million for the three and six months ended June 30, 2025, respectively, and $1.0 million and $1.9 million for the three and six months ended June 30, 2024, respectively.

Note 17. Subsequent Events

Business Combination

On July 9, 2025, the Company completed an acquisition of 100% of ANP, an innovation-driven company, which has developed multiple proprietary product platforms. The acquisition was structured as a combination of cash and stock, with a preliminary consideration of $4.2 million, net of cash received. The consideration includes a contingent consideration of approximately $5.7 million worth of the Company’s common stock based on ANP’s achievement of certain milestones as described in the acquisition agreement. The Company has not yet completed the purchase accounting due to the timing of the acquisition, and it continues to evaluate the estimated fair values of the assets acquired and the liabilities assumed. Accordingly, the fair value of the assets and liabilities acquired, including goodwill and other intangible assets, is not yet available.

This acquisition enables the Company to secure ownership of the patents previously licensed from ANP, which are currently utilized in ongoing clinical studies. By securing full ownership of these intellectual property rights, the Company aims to enhance its control over the development and commercialization of related therapeutic candidates, thereby aligning with its strategic objectives to advance clinical programs.

One Big Beautiful Bill Act

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act, or OBBBA. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation and domestic research cost expensing. ASC 740, “Income Taxes,” requires the effects of changes in tax laws to be recognized in the period in which the legislation is enacted.

As the enactment of the OBBBA occurred after the balance sheet date of June 30, 2025, the consolidated financial statements for the three and six months ended June 30, 2025, do not reflect any adjustments related to the OBBBA. The Company is still evaluating the full impact of the OBBBA. Any changes resulting from this evaluation will be reflected in the period in which the legislation was enacted.

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

The following discussion and analysis of our financial condition and results of operations should be read together with our condensed consolidated financial statements and related notes included in this report.

Risk Factors” in Part I of the 2024 Annual Report and “Item 1A. Risk Factors” in Part II of our Quarterly Report for the quarter ended March 31, 2025, filed with the SEC on May 2, 2025, or our Q1 2025 Quarterly Report. In addition, our performance in any period is affected by a number of other factors. See the description of some of the material factors affecting our performance in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Business Risks and Uncertainties and Other Factors Affecting Our Performance” of the 2024 Annual Report and in “Item 2 Management’s Discussion and Analysis of Financial Condition and Results of Operations- Factors Affecting Our Performance” in our Q1 2025 Quarterly Report. In particular and as previously mentioned, we continue to be subject to audits and investigations by government agencies, including audits from applicable tax authorities, and continue to navigate changes and the effects of recent international trade policies and tax legislation. The final results of these matters are uncertain and could materially affect our business and results of operations.

Revenue increased by $10.8 million, or 15%, from $71.0 million in the three months ended June 30, 2024, to $81.8 million in the three months ended June 30, 2025. The increase in revenue between periods was driven by increases of $4.1 million in precision diagnostics, $4.7 million in anatomic pathology, and $2.6 million in BioPharma services, partially offset by a decrease of $0.7 million in COVID-19 testing.

Revenue increased by $19.8 million, or 15%, from $135.5 million in the six months ended June 30, 2024, to $155.3 million in the six months ended June 30, 2025. The increase in revenue between periods was driven by increases of $10.8 million in precision diagnostics, $6.9 million in anatomic pathology, and $4.1 million in BioPharma services, partially offset by a decrease of $2.0 million in COVID-19 testing.

The increase in precision diagnostics revenue was driven by growth in our reproductive health services and continued strength in legacy diagnostic offerings. Anatomic pathology services revenue increased primarily due to the absence of weather-related disruptions and client losses that had affected the prior year; in addition, the investment that we have made in digital pathology is starting to show return. BioPharma services revenue increased largely as a result of the timing of service projects, though this revenue is expected to remain variable due to the long sale cycles and fluctuations in project timing. Additionally, COVID-19 related revenue recognized in 2024 was due to variable consideration recognized for services completed in prior periods. We do not expect future material revenues from our COVID-19 testing services.

We believe the factors that will affect our ability to grow these revenue streams are 1) the average price point we offer and the reimbursement rate from insurance payors; 2) the concentration of our payor base; 3) the competitive advantage we have due to our broad and flexible test menu, detection rate, and turnaround times; and 4) growth in size of an addressable market. Estimated collection amounts from insurance payors are subject to the complexities and ambiguities of billing, reimbursement regulations and claims processing, as well as considerations unique to Medicare and Medicaid programs. Because our proprietary technology platform allows for rapid scaling of a broad, flexible testing menu, we can offer our customers more scalable and affordable testing. Going forward, we will strive to maintain this competitive advantage and emphasize this in our marketing efforts to grow our testing revenue.

Our customer base includes insurance, institutional, and individual payors. In some periods, our revenue is concentrated on a smaller number of customers. For the laboratory services segment, aggregating customers that are under common control, one customer comprised $17.6 million, or 22%, of our revenue in the three months ended June 30, 2025, and contributed $35.2 million, or 23%, of total revenue in the six months ended June 30, 2025. The same customer contributed $16.9 million, or 24%, of our revenue in the three months ended June 30, 2024, and contributed $29.6 million, or 22%, of total revenue in the six months ended June 30, 2024. To reduce this revenue risk, we will focus on increasing the number of customers and thereby reducing the concentration.

Revenue from non-U.S. sources decreased by $1.2 million, or 18%, from $6.8 million in the three months ended June 30, 2024, to $5.6 million in the three months ended June 30, 2025. Revenue from non-U.S. sources decreased by $2.2 million, or 17%, from $13.5 million in the six months ended June 30, 2024, to $11.2 million in the six months ended June 30, 2025. The decrease was primarily due to a one-time licensing arrangement recognized in the prior period that did not recur in the current period. Additionally, the Company started to group revenue from Puerto Rico and the U.S. Virgin Islands as United States geographic revenue beginning in the third quarter of 2024. These revenues had historically been grouped as non-U.S.

Our consolidated cost of revenue increased by $2.8 million, or 6%, from $44.5 million in the three months ended June 30, 2024, to $47.4 million in the three months ended June 30, 2025. The increase was primarily due to increases of $1.9 million in personnel expenses, $0.7 million in reagent and supply costs, $0.6 million in consulting and outside labor costs, $0.5 million in depreciation expenses, and partially offset by decreases of $0.6 million in facility expenses, $0.2 million in shipping and handling expenses, and $0.1 million in software and software licensing.

Our consolidated cost of revenue increased by $5.6 million, or 6%, from $86.9 million in the six months ended June 30, 2024, to $92.5 million in the six months ended June 30, 2025. The increase was primarily due to increases of $3.0 million in personnel costs due to increased headcount, $1.6 million in reagent and supply costs, $0.5 million in depreciation expenses, $0.4 million in office expenses, $0.4 million in consulting and outside labor costs, $0.3 million in facility expenses, $0.3 million in software and software licensing, and partially offset by a decrease of $1.0 million in shipping and handling expenses.

Our consolidated cost of revenues as a percentage of revenue decreased from 63% in the three months ended June 30, 2024, to 58% in the three months ended June 30, 2025. Our consolidated cost of revenues as a percentage of revenue decreased from 64% in the six months ended June 30, 2024, to 60% in the six months ended June 30, 2025.

Our gross profit increased by $7.9 million, or 30%, from $26.5 million in the three months ended June 30, 2024, to $34.4 million in the three months ended June 30, 2025, and increased $14.2 million, or 29%, from $48.6 million in the six months ended June 30, 2024, to $62.8 million in the six months ended June 30, 2025. Our gross profit as a percentage of revenue, or gross margin, increased from 37% in the three months ended June 30, 2024, to 42% in the three months ended June 30, 2025, and 36% in the six months ended June 30, 2024, to 40% in the six months ended June 30, 2025. This is driven by the increased revenue and efforts of optimizing cost structures.

Laboratory services

During the three and six months ended June 30, 2025, research and development expenses for our laboratory services segment remained largely in line with prior-year periods. This consistent spending supports advancing our core technology and expanding future testing services. Personnel costs, including bonuses and equity-based compensation, were the primary driver, totaling approximately $6.8 million and $6.4 million in the three months ended June 30, 2025, and 2024, respectively, and $13.1 million in each of the six months ended June 30, 2025, and 2024. Reagent and supply costs were $0.3 million for each of the three months ended June 30, 2025, and 2024 and $0.7 million for each of the six months ended June 30, 2025, and 2024. All other expense categories including facilities, depreciation, software and software licensing, are not individually significant and have remained stable. We expect research and development expenses for our laboratory services segment continue to remain consistent for the remainder of 2025.

Therapeutic Development

For the therapeutic development segment, the research and development expenses in the three months ended June 30, 2025, consisted of $3.1 million in contract research organizations, or CRO, costs, $2.6 million in personnel costs, including equity-based compensation, and $0.2 million in depreciation expenses. In the three months ended June 30, 2024, these expenses comprised $3.3 million in CRO costs, $2.6 million of personnel costs, including equity-based compensation, and $0.2 million in depreciation expenses.

For the therapeutic development segment, the research and development expenses in the six months ended June 30, 2025, consisted of $5.7 million in CRO costs, $5.1 million in personnel costs, including equity-based compensation, and $0.3 million in depreciation expenses. In the six months ended June 30, 2024, these expenses comprised $5.6 million in CRO costs, $4.2 million of personnel expenses, including equity-based compensation, and $0.3 million in depreciation expenses.

Research and development expenses for the therapeutic development segment remained flat for each of the three months ended June 30, 2025, and 2024. Research and development expenses for the therapeutic development segment increased by $1.1 million, or 11%, from $10.3 million in the six months ended June 30, 2024, to $11.3 million in the six months ended June 30, 2025. The increase was primarily driven by increases of $0.9 million in personnel costs, including equity-based compensation expense, and $0.1 million in CRO costs. The overall increase was attributed to the advancement and continuation of the clinical study of FID-007, along with FID-022. In the three and six months ended June 30, 2025, approximately $0.6 million and $1.6 million, respectively, was incurred for the preclinical development of FID-022, whereas related costs in the three and six months ended June 30, 2024, were minimal. Expenses for our therapeutic development segment will be influenced by our ability to progress our therapeutic candidates through development with the Food and Drug Administration, or the FDA, the timing of which can be uncertain and delayed due to a variety of factors beyond our control, including recently announced staff reductions at the FDA which may affect the FDA’s ability to provide any required approvals or review in a timely manner or in the timelines expected.

Looking ahead, we expect research and development expenses to continue increasing as clinical trials progress for FID-007, FID-022, and other preclinical studies.

Selling and Marketing

Our consolidated selling and marketing expenses increased by $3.7 million, or 43%, from $8.6 million in the three months ended June 30, 2024, to $12.3 million in the three months ended June 30, 2025. The increase in consolidated selling and marketing expenses was due to increases of $1.6 million in personnel costs, $1.5 million in advertising and marketing expenses, $0.3 million in software and software licensing, and $0.2 million in consulting and outside labor.

Our consolidated selling and marketing expenses increased by $3.2 million, or 18%, from $17.6 million in the six months ended June 30, 2024, to $20.8 million in the six months ended June 30, 2025. The increase in consolidated selling and marketing expenses was due to increases of $1.3 million in personnel costs, $1.3 million in advertising and marketing expenses, $0.3 million in consulting and outside labor, and $0.2 million in software and software licensing.

General and Administrative

Our consolidated general and administrative expenses increased by $5.1 million, or 24%, from $21.3 million in the three months ended June 30, 2024, to $26.4 million in the three months ended June 30, 2025. The increase in consolidated general and administrative expenses was due to increases of $4.3 million in provision for credit losses, $0.7 million in personnel costs, $0.5 million in software and software licensing fees, $0.5 million in consulting and outside labor costs, $0.4 million in insurance charges, and partially offset by decreases of $0.9 million in facility expenses and $0.5 million in depreciation expenses.

Our consolidated general and administrative expenses increased by $8.9 million, or 21%, from $42.8 million in the six months ended June 30, 2024, to $51.7 million in the six months ended June 30, 2025. The increase in consolidated general and administrative expenses was due to increases of $8.8 million in provision for credit losses, $1.7 million in personnel costs, $0.7 million in software and software licensing fees, $0.7 million in consulting and outside labor costs, $0.6 million in insurance charges, $0.3 million in bank charges, $0.3 million in office expenses, and partially offset by decreases of $2.0 million in facility expenses, $1.3 million in depreciation expenses, $0.5 million in legal and professional fees, and $0.3 million in accounting expenses.

Amortization of Intangible Assets

Our consolidated amortization of intangible assets represents amortization expenses on the intangible assets that arose from the business combinations in 2022 and 2021, and a patent purchased in 2021. The Company did not have any new business combinations in the current period.

Other Income (Expenses)

Other income (expense) is primarily comprised of interest income, which was $8.1 million and $16.1 million in the three and six months ended June 30, 2025, respectively, $7.7 million and $15.1 million in the three and six months ended June 30, 2024, respectively. This interest income included interest earned on marketable securities and realized gain or loss on sale of marketable securities. The change in interest income was primarily due to net loss realized from sale of marketable securities in prior year. Other expenses primarily consisted of a one-time, non-cash impairment of a prior investment as discussed further in Note 4 of the financial statements included in this quarterly report.

Benefit from Income Taxes

Benefit from income taxes was $2.3 million and $2.1 million for the three and six months ended June 30, 2025, respectively, compared with $2.1 million and $2.5 million for the three and six months ended June 30, 2024, respectively. The Company’s effective tax rate was 11% and 6% the three and six months ended June 30, 2025, respectively, compared to 19% and 10% for the three and six months ended June 30, 2024, respectively. The change in the effective tax rate compared to prior period is due to the valuation allowance that precludes us from recognizing the benefit from our net operating losses.

On July 4, 2025, President Trump signed into law the OBBBA. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation and domestic research cost expensing. ASC 740, “Income Taxes,” requires the effects of changes in tax laws to be recognized in the period in which the legislation is enacted.

As the enactment of the OBBBA occurred after the balance sheet date of June 30, 2025, the consolidated financial statements for the three and six months ended June 30, 2025, do not reflect any adjustments related to the OBBBA. We are still evaluating the full impact of the OBBBA. Any changes resulting from this evaluation will be reflected in the period in which the legislation was enacted.

Net Loss Attributable to Noncontrolling Interest

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

Liquidity and Capital Resources

Liquidity and Sources of Cash

We had $777.5 million and $828.6 million in cash, cash equivalents, restricted cash, and marketable securities as of June 30, 2025, and December 31, 2024, 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 June 30, 2025, and December 31, 2024.

Our main uses of cash are for capital expenditures, primarily in buildings, building improvements, and medical laboratory equipment, as well as for stock repurchases, supporting our operations, and to fund strategic acquisitions as we continue to invest in and seek to grow our business. Cash used to cover 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 expect our existing cash, cash equivalents, restricted cash, and short-term marketable securities will continue to be sufficient to meet our anticipated cash requirements for at least the next 12 months. Cash provided by operations has significantly contributed to our ability to meet our liquidity needs, including paying for capital expenditures, however, cash provided by our operations has in the past experienced fluctuations 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. We intend to improve our profitability by improving margins and expanding in new markets for our tests, but these efforts are subject to risks, including those described in Item 1A of the 2024 Annual Report, and may not be successful. 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 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.

Cash Flows

The following table summarizes our cash flows from continuing operations for each of the periods presented:


	Six Months Ended June 30,
	2025			2024
	(in thousands)
Net cash (used in) provided by operating activities	$	(34,602	)	$	11,551
Net cash provided by (used in) investing activities	$	81,133		$	(39,882	)
Net cash used in financing activities	$	(13,810	)	$	(3,953	)

Operating Activities

During the six months ended June 30, 2025, our operations used $34.6 million of cash, as compared to $11.6 million provided in the six months ended June 30, 2024. The decrease in cash from operating activities in the six months ended June 30, 2025, as compared with the corresponding period in 2024, was primarily due to the purchase of IRA tax credits of $33.8 million and timing of cash receipts from customers and cash payments for operating expenses. We expect to incur more operating expenses and use more cash in operating activities in the coming quarters as a result of our planned and ongoing clinical trials for FID-007 and FID-022, and as we continue to invest resources to grow our laboratory services business.

Investing Activities

The cash provided by or used in investing activities are impacted by capital expenditures for operation needs and timing of payments, timing of maturities of marketable securities, and discretionary business combinations and other investment.

Cash provided by investing activities in the six months ended June 30, 2025 was $81.1 million, which primarily represents $92.7 million in the maturities of marketable securities, partially offset by $11.5 million related to the purchase of fixed assets consisting mainly of building improvement, medical laboratory equipment, and computer hardware.

Cash used in investing activities in the six months ended June 30, 2024, was $39.9 million, which primarily represents $258.8 million in purchase of marketable securities and $17.0 million related to the purchase of fixed assets, including real estate, partially offset by $160.1 million related to maturities of marketable securities and $75.6 million related to proceeds from the sale of marketable securities.

Financing Activities

Cash used in financing activities in the six months ended June 30, 2025, was $13.8 million, which primarily related to $10.9 million used in the repurchase of common stock and $2.2 million used in common stock withholding for employee tax obligations.

Cash used in financing activities in the six months ended June 30, 2024, was $4.0 million, which primarily related to $2.2 million used in common stock withholding for employee tax obligations, $1.2 million used in the repayment of notes payable, and $0.2 million for repurchase of common stock.

We did not expect to use any credit facilities due to the strong cash position as of June 30, 2025.

Stock Repurchase Program

During the three and six months ended June 30, 2025, we repurchased 0.2 million and 0.6 million shares of our common stock, respectively, at an aggregate cost of $3.0 million and $10.9 million, respectively, under the stock repurchase program. During the three and six months ended June 30, 2024, we repurchased zero and 10,000 shares of our common stock, respectively, at an aggregate cost of zero and $0.2 million, respectively, under the stock repurchase program. As of June 30, 2025, a total of approximately $139.6 million remained available for future repurchases of our common stock under our stock repurchase program.

We did not have, and do not currently have, any off-balance sheet arrangements during the periods presented, as defined in the rules and regulations of the SEC, that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

For quantitative and qualitative disclosures about market risk, see Part II, “Item 7A, Quantitative and Qualitative Disclosures About Market Risk,” in the 2024 Annual Report. There were no material changes during the six months ended June 30, 2025.

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 principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of June 30, 2025. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2025.

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 and six months ended June 30, 2025, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

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.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may be involved in legal proceedings arising in the ordinary course of our business. As disclosed in Note 8, Debt, Commitments, and Contingencies, to the condensed consolidated financial statements, we are engaged in certain legal investigations, audits, and voluntary disclosure processes, and the disclosure set forth in Note 8 relating to these certain legal matters is incorporated herein by reference.

The outcome of these matters are inherently uncertain, and there can be no assurances that favorable outcomes will be obtained.

Regardless of outcome, litigation can have an adverse impact on us due to defense and settlement costs, diversion of management resources, negative publicity, and reputational harm, among other factors.

Item 1A. Risk Factors.

There have been no material changes to the risk factors set forth in Part I, “Item 1A, Risk Factors,” of the 2024 Annual Report and as set forth in Part II, “Item 1A. Risk Factors” of our Form 10-Q for the quarter ended March 31, 2025, filed with the SEC on May 2, 2025.

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

Use of Proceeds from Registered Securities

To date, we have used $267.9 million of the net proceeds from sales of our common stock to fund the Company’s operations and business combinations. All other net proceeds from sales of our common stock are invested in investment-grade and interest-bearing securities, such as U.S. government and U.S. agency debt securities, corporate bonds, and municipal bonds. There has been no material change in the planned use of proceeds from the sales of our common stock from that described in the applicable prospectus.

Information on Share Repurchases

In March 2022, our Board of Directors authorized a $250.0 million stock repurchase program. The stock repurchase program has no expiration from the date of authorization. Under the stock repurchase program, the Company may repurchase shares from time to time in the open market or in privately negotiated transactions. All purchases listed below were made in the open market at prevailing market prices and were executed pursuant to trading plans we adopted pursuant to Rule 10b5-1 under the Exchange Act.

The number of shares of common stock repurchased by the Company under the stock repurchase program and the average price paid per share for the three months ended June 30, 2025, are as follows:

Item 5. Other Information

Rule 10b5-1 trading arrangements

During the three months ended June 30, 2025, none of our directors or officers adopted or terminated “Rule 10b5-1 trading arrangement” as defined in Item 408 of Regulation S-K. However, Ming Hsieh, our Chief Executive Officer, terminated a prepaid variable forward agreement, or the Prepaid Agreement, dated as of September 14, 2022, with an unaffiliated bank, which constitutes a “non‑Rule 10b5‑1 trading arrangement” as defined in Item 408 of Regulation S-K. Under the Prepaid Agreement, Mr. Hsieh pledged up to 0.8 million shares of our common stock, or the Pledged Shares. On June 9, 2025, Mr. Hsieh elected to terminate the arrangement. Upon the payment of $16.4 million, the Pledged Shares were no longer subject to the Prepaid Agreement.

Segment Reporting, CODM, Individual Title and Position or Group Name [Extensible Enumeration]	srt:ChiefExecutiveOfficerMember
Segment reporting, CODM, profit (loss) measure, description	The financial information regularly provided to the CODM includes various performance metrics by reportable segment, such as gross profit, operating income or loss, income or loss before income taxes, net income or loss from consolidated operations, and net income or loss attributable to Fulgent, all presented in accordance with U.S. GAAP. Additionally, the CODM receives these metrics on a non-GAAP basis, which excludes the impact of equity-based compensation expenses, goodwill impairment losses, amortization of intangible assets, and restructuring costs, if applicable. Although multiple financial metrics are provided, the CODM primarily relies on adjusted operating income or loss, on a non-GAAP basis, to evaluate segment performance and allocate resources as this measure enhances the CODM's ability to compare past financial performance with current performance and analyze underlying business performance and trends.
