Natera Inc

1. Description of Business

Natera, Inc. (the “Company”) was formed in the state of California as Gene Security Network, LLC in November 2003 and incorporated in the state of Delaware in January 2007. The Company is a diagnostics company with proprietary molecular and bioinformatics technology that it is applying to change the management of disease worldwide. The Company’s cell-free DNA (“cfDNA”) technology combines its novel molecular assays, which reliably measure many informative regions across the genome from samples as small as a single cell, with its statistical algorithms which incorporate data available from the broader scientific community to identify genetic variations covering a wide range of serious conditions with high accuracy and coverage. The Company focuses on applying its technology to three main areas of healthcare – women’s health, oncology and organ health. In the women’s health space, the Company develops and commercializes non- or minimally- invasive tests to evaluate risk for, and thereby enable early detection of, a wide range of genetic conditions, such as Down syndrome. In oncology, the Company commercializes, among others, a personalized blood-based DNA test to detect molecular residual disease and monitor for disease recurrence across a broad range of cancer types. The Company’s third area of focus is organ health, with tests to assess kidney, heart, and lung transplant rejection as well as genetic testing for chronic kidney disease. The Company operates laboratories in Austin, Texas and San Carlos, California certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) providing a host of cell-free DNA-based molecular testing services. The Company determines its operating segments based on the way it organizes its business to make operating decisions and assess performance. The Company operatesone segment, the development and commercialization of molecular testing services, applying its proprietary technology in the fields of women’s health, oncology and organ health.

The Company’s key product offerings include its Panorama Non-Invasive Prenatal Test (“Panorama”) that screens for chromosomal abnormalities of a fetus as well as in twin pregnancies, typically with a blood draw from the mother; Horizon Carrier Screening (“Horizon”) to determine carrier status for a large number of severe genetic diseases that could be passed on to the carrier’s children; its Signatera molecular residual disease test (“Signatera”) to detect circulating tumor DNA in patients previously diagnosed with cancer to assess molecular residual disease, monitor for recurrence, and evaluate treatment response; and its Prospera test, to assess organ transplant rejection in patients who have undergone kidney, heart, or lung transplantation. All testing is available principally in the United States. The Company also offers its Panorama test to customers outside of the United States, primarily in Europe. The Company also offers Constellation, a cloud-based software platform that enables laboratory customers to gain access through the cloud to the Company’s algorithms and bioinformatics in order to validate and launch their own tests based on the Company’s technology.

2. Summary of Significant Accounting Policies

During the six months ended June 30, 2024, there were no material changes to the Company’s significant accounting policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (filed on February 29, 2024).

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. The unaudited interim condensed consolidated financial information includes only adjustments of a normal recurring nature necessary for a fair presentation of the Company’s results of operations, financial position, changes in stockholders’ equity, and cash flows. The results of operations for the six months ended June 30, 2024, are not necessarily indicative of the results for the full year or the results for any future periods. The condensed consolidated balance sheet as of December 31, 2023 has been derived from audited financial statements at that date. These financial statements should be read in conjunction with the audited financial statements, and related notes for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 29, 2024.

Some items in the prior period financial statements were reclassified to conform to the current presentation.

Liquidity Matters

The Company has incurred net losses since its inception and anticipates net losses for the near future. The Company had a net loss of $105.1 million for the six months ended June 30, 2024 and an accumulated deficit of $2.5 billion as of June 30, 2024. As of June 30, 2024, the Company had $796.8 million in cash, cash equivalents, and restricted cash, $90.3 million in marketable securities, an $80.4 million outstanding balance on its Credit Line (as defined in Note 10,Debt) including accrued interest and $287.5 million of outstanding principal on its 2.25% Convertible Senior Notes (the “Convertible Notes”). The Company is required to maintain a minimum of at least $150.0 million in its UBS accounts as collateral for its Credit Line. As of June 30, 2024, the Company had $20.0 million remaining and available on its Credit Line.

While the Company has introduced multiple products that are generating revenues, these revenues have not been sufficient to fund all operations and business plans. Accordingly, the Company has funded the portion of operating costs that exceeds revenues through a combination of equity issuances, debt issuances, and other financings.

The Company continues to invest in the development and commercialization of its existing and future products and, consequently, it will need to generate additional revenues to achieve future profitability and may need to raise additional equity or debt financing. If the Company raises additional funds by issuing equity securities, its stockholders will experience dilution. Additional debt financing, if available, may involve covenants restricting its operations or its ability to incur additional debt. Any additional debt financing or additional equity that the Company raises may contain terms that are not favorable to it or its stockholders and requires significant debt service payments, which diverts resources from other activities. Additional financing may not be available when necessary, or in amounts or on terms acceptable to the Company. If the Company is unable to obtain additional financing, it may be required to delay the development and commercialization of its products and significantly scale back its business and operations.

On July 19, 2024, the Company announced its decision to redeem all of its outstanding 2.25% Convertible Senior Notes due 2027. The redemption is scheduled for October 11, 2024 (the “Redemption Date”). The redemption price for the Convertible Notes is equal to 100% of the principal amount of the Convertible Notes to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date. The Company elected physical settlement with shares of its common stock as the settlement method to apply to all conversions of the Convertible Notes. Based on the conversion terms of the Convertible Notes and the market price of its common stock, the Company expects that substantially all outstanding Convertible Notes will be converted into shares of the Company’s common stock prior to the Redemption Date. As a result, the Company does not expect that its decision to redeem the Convertible Notes will have a material effect on its liquidity.

In September 2023, the Company completed an underwritten equity offering and sold 4,550,000 shares of its common stock at a price of $55 per share to the public. Before estimated offering expenses of $0.4 million, the Company received proceeds of approximately $235.8 million net of the underwriting discount.

On September 10, 2021, the Company entered into an agreement with a third party for an asset acquisition where the acquired asset was in-process research and development primarily in exchange for an equity consideration payment. In addition, pursuant to the agreement, certain employees of the third party became employees of the Company. The third party was a biotechnology company focused on oncology. The total upfront acquisition consideration amounts to $35.6 million composed of the issuance of 276,346 shares of the Company's common stock with a fair value of $30.9 million, approximately $3.9 million of cash consideration, assumed net liabilities of $0.2 million, as well as $0.6 million of acquisition related legal and accounting costs directly attributable to the acquisition of the asset. The Company accounted for the transaction as an asset acquisition as substantially all of the estimated fair value of the gross assets acquired was concentrated in a single identified in-process research and development asset (“IPR&D”) thus satisfying the requirements of the screen test in Accounting Standards Update (“ASU”) 2017-01Business Combinations (Topic 805): Clarifying the Definition of Business. The estimated fair value of the acquired workforce was not significant. The Company concluded the acquired IPR&D has no alternative-future use and accordingly expensed approximately $35.6 million, on the day the transaction closed as research and development expense, which is reflected in its consolidated statement of operations.

Further, additional consideration aggregating up to approximately $35.0 million was estimated to be paid via issuance of an estimated 269,547 additional shares of the Company’s common stock, consistent with the registration statement filed with the SEC on September 10, 2021, upon achievement of defined milestones relating to product development, commercial launch and continued employment of certain selling shareholders, each of which was revalued at each reporting date and amount of compensation expense was adjusted accordingly and reported in research and development expenses. In November 2022, the terms of the payment for any remaining consideration were modified, resulting in $10.0 million of consideration paid in December 2022 and $15.0 million of consideration paid in March 2023, with such consideration primarily consisting of the Company’s common stock.

Based on the Company’s current business plan, the Company believes that its existing cash and marketable securities will be sufficient to meet its anticipated cash requirements for at least 12 months after August 8, 2024.

Principles of Consolidation

The accompanying condensed consolidated financial statements include all the accounts of the Company and its subsidiaries. The Company established a subsidiary that operates in the state of Texas to support the Company’s laboratory and operational functions. The Company established a subsidiary that operates in Canada following the acquisition of the IPR&D asset. All intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles (GAAP) in the United States requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include the allowance for doubtful accounts, the operating right-of-use assets and the associated lease liabilities, the average useful life for property and equipment including impairment estimates, deferred revenues associated with unsatisfied performance obligations, accrued liability for potential refund requests, stock-based compensation, the fair value of options, income tax uncertainties, and the expected consideration to be received from contracts with customers, insurance payors, and patients. These estimates and assumptions are based on management's best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors, including contractual terms and statutory limits; however, actual results could differ from these estimates and could have an adverse effect on the Company's financial statements.

Investments

Investments consist primarily of debt securities such as U.S. Treasuries, U.S. agency and municipal bonds. Management determines the appropriate classification of securities at the time of purchase and re-evaluates such determination at each balance sheet date. The Company generally classifies its entire investment portfolio as available-for-sale. The Company views its available-for-sale portfolio as available for use in current operations. Accordingly, the Company classifies all investments as short-term, irrespective of maturity date. Available-for-sale securities are carried at fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss), which is a separate component of stockholders’ equity.

The Company classifies its investments as Level 1 or 2 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves. The Company holds Level 2 securities which are initially valued at the transaction price and subsequently valued by a third-party service provider using inputs other than quoted prices that are observable either directly or indirectly, such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. The Company performs certain procedures to corroborate the fair value of these holdings.

Available-for-sale debt securities.The amended guidance from ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, requires the measurement of expected credit

losses for available-for-sale debt securities held at the reporting date over the remaining life based on historical experience, current conditions, and reasonable and supportable forecasts. The Company evaluated its investment portfolio under the available-for-sale debt securities impairment model guidance and determined the Company’s investment portfolio is composed of low-risk, investment grade securities and thus has not recorded an expected credit loss for its investment portfolio. Further, gross unrealized losses on available for sale securities were not material at June 30, 2024.

Accounts Receivable

Trade accounts receivable and other receivables. The allowance for doubtful accounts for trade accounts receivable is based on the Company’s assessment of the collectability of accounts related to its clinics and laboratory partner customers. The Company regularly reviews the allowance by considering factors such as historical experience, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. See Note 6,Balance Sheet Components, for a roll-forward of the allowance for doubtful accounts related to trade accounts receivable for three months and six months ended June 30, 2024 and 2023. The Company recognizes revenue under Accounting Standards Codification (“ASC”) Topic 606,Revenue from Contracts with Customers (“ASC 606”) and applies a constraint to the estimated variable consideration such that it is not probable that a significant reversal will occur. When assessing the total consideration expected to be received from insurance carriers and patients, a certain percentage of revenues is further constrained for estimated refunds. After applying the ASC 606 constraint, the Company assessed for credit losses and allowance for doubtful accounts and determined an incremental credit loss was not needed given the quality of the insurance payors from whom such receivables are expected to be collectible and the relatively short duration over which the majority of receivables are collected. Accordingly, the Company currently does not have an incremental credit loss reserve nor allowance for doubtful accounts against accounts receivable for insurance and patient payors due to the average selling price calculations which incorporate these risks as net receivables are recorded.

Inventory

Inventory is recorded at the lower of cost or net realizable value, determined on a first-in, first-out basis. Inventory consists entirely of supplies, which the Company consumes when providing its test reports, and therefore, the Company does not maintain any finished goods inventory. The Company enters into inventory purchases commitments so that it can meet future delivery schedules based on forecasted demand for its tests.

The Company uses judgment to analyze and determine if the composition of its inventory is obsolete, slow-moving or unsalable and frequently reviews such determinations. A write down of specifically identified unusable, obsolete, slow-moving or known unsalable inventory in the period is first recognized by using a number of factors including product expiration dates and scrapped inventory. Any write-down of inventory to net realizable value establishes a new cost basis and will be maintained even if certain circumstances suggest the inventory is recoverable in subsequent periods. Costs associated with the write-down of inventory are recorded to cost of revenue on our consolidated statements of operations. The Company makes assumptions about future demand, market conditions and the release of new products that may supersede older products. However, if actual market conditions are less favorable than anticipated, additional inventory write-downs may be required.

Other Assets

In January 2024, the Company acquired from Invitae Corp. (“Invitae”) certain assets relating to Invitae’s non-invasive prenatal screening and carrier screening business. The transaction price of $10.5 million consisted of $10.0 million in upfront payment costs and approximately $0.5 million of other transaction costs which were capitalized as intangible assets over an estimated useful life often years. An additional payment of up to $42.5 million may be made should the Company achieve certain customer volume retention targets and based on certain legal outcomes.

Accumulated Other Comprehensive Income (Loss)

Comprehensive loss and its components encompass all changes in equity other than those with stockholders, and include net loss, unrealized gains and losses on available-for-sale marketable securities and foreign currency translation adjustments.

The change in net unrealized loss on available-for-sale securities is due to increased market volatility. The Company has assessed the unrealized loss position for available-for-sale securities and determined that an allowance for credit loss was not necessary.

Revenue Recognition

The Company recognizes revenue under, ASC 606, using the following five step process:

The Company uses the most likely amount method of estimating variable consideration. The total consideration which the Company expects to collect in exchange for the Company’s products is an estimate and may be fixed or variable, and is primarily based on historical cash collections for tests delivered, as adjusted for current expectations. Current expectations of cash collections factor in changes in reimbursement rate trends, past events not expected to recur, and future known changes such as anticipated contractual pricing changes or changes to insurance coverage. For insurance carriers and product types with similar reimbursement characteristics, the Company uses a portfolio approach to estimate variable consideration. The Company also applies a constraint to the estimated variable consideration when it assesses whether it is probable that a significant reversal in the amount of cumulative revenue may occur in future periods.

When assessing the total consideration expected to be received from insurance carriers and patients, a certain percentage of revenues is further constrained for estimated refunds.

See Note 3,*Revenue Recognition,*for detailed discussions of product revenues, licensing and other revenues, and how the five steps described above are applied.

Fair Value

The Company discloses the fair value of financial instruments for financial assets and liabilities for which the value is practicable to estimate. Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

Related Party

On December 6, 2021, the Company participated along with certain other investors in the series B financing of MyOme, Inc. (“MyOme”), and purchased preferred shares and warrants in exchange for a cash payment of approximately $4.0 million. The Company does not hold a seat on MyOme’s board of directors. The Company’s investment in MyOme is recorded at cost andno impairment was identified as of June 30, 2024. The following are the Company’s related persons and the basis of each such related person’s relationship with MyOme:

None of the related party investments in MyOme by our executives and directors noted above were at the behest of the Company nor funded by the Company.

In February 2024, the Company entered into a collaboration and commercialization agreement (the “Collaboration Agreement”) with MyOme pursuant to which the parties will partner to offer certain genetic testing services to be developed and funded solely by MyOme and overseen by a joint steering committee. The Company will assist MyOme with commercial activities. In connection with the Collaboration Agreement, the Company received a 10-year warrant to purchase 3,058,485 shares of MyOme's common stock at an exercise price of $0.25 per share, which will vest upon a MyOme liquidity event (as such terms are defined in MyOme's certificate of incorporation). The warrants were valued using the Black-Scholes valuation model on the date of acquisition and are accounted for using the measurement alternative. No impairment was identified as of June 30, 2024. The warrants have been included within other assets and deferred revenue, long-term portion and other liabilities, which will be recognized as a reduction of selling and marketing expense upon commercialization and sale of the products contemplated under the Collaboration Agreement. Subject to the Company's achievement of certain commercialization milestones, the Company may receive additional warrants to purchase MyOme’s Series B Preferred Stock. To the extent the genetic testing services are successfully commercialized, the Company will owe certain royalty payments to MyOme. Should the Company exercise all its MyOme common stock warrants, the Company would hold an accumulated 12.4% of MyOme on a fully diluted basis.

Risk and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash, cash equivalents, and restricted cash, accounts receivable and investments. The Company limits its exposure to loss by placing its cash in financial institutions with high credit ratings. The Company's cash may consist of deposits held with banks that may at times exceed federally insured limits of $250,000 per customer. The Company performs evaluations of the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution.

For the three and six months ended June 30, 2024, and 2023, there wereno customers exceeding 10% of total revenues on an individual basis. As of June 30, 2024 and December 31, 2023, there wereno customers with an outstanding balance exceeding 10% of net accounts receivable.

For the three months ended June 30, 2024 and 2023, approximately 10.3% and 12.5%, respectively, of total revenue were paid by Medicare on behalf of multiple customers. For the six months ended June 30, 2024 and 2023, approximately 10.9% and 13.2%, respectively, of total revenue were paid by Medicare on behalf of multiple customers.

As of June 30, 2024 and December 31, 2023, approximately 8.8% and 10.2%, respectively, of accounts receivable are expected to be paid by Medicare on behalf of multiple customers.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) under its accounting standard codifications or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed below, the Company believes that the impact of accounting standards updates recently issued that are not yet effective will not have a material impact on its financial position or results of operations upon adoption.

New Accounting Pronouncements Not Yet Adopted

In March 2020, ASU 2020-04,Reference Rate Reform (Topic 848) was issued which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. ASU 2022-06, orReference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The Company does not expect adoption of this standard to have a material impact on its consolidated financial statements.

In November 2023, ASU 2023-07,Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, was issued which requires disclosure of incremental segment information on an interim and annual basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal periods beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on its consolidated financial statements.

In December 2023, ASU 2023-09,Income Taxes - Improvements to Income Tax Disclosures, was issued, which requires enhanced disclosures in connection with an entity's effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. The standard will be effective for annual periods beginning after December 15, 2024. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements.

3. Revenue Recognition

The Company recognizes revenues when, or as, performance obligations in the contracts are satisfied, in the amount reflecting the expected consideration to be received from the goods or services transferred to the customers.

Product Revenues

Product revenues are derived by performing genetic testing services and the Company’s performance obligation is complete when test results are delivered to a clinic or patient, who are considered the customer for such services as further discussed below.

Additionally, the Company enters into agreements with pharmaceutical companies to utilize the Company’s Signatera tests typically to study new cancer treatments or to validate the outcomes of clinical trials for which the pharmaceutical companies are identified as customers. Such arrangements generally involve performing whole exome sequencing services and the testing of patient samples to detect cancer mutations using its Signatera test. In addition to performing Signatera tests, these agreements typically include certain activities to fulfill the contract, such as customer data setup and management and ongoing reporting. Each test result is billable to customers upon delivery and the personalized cancer profile also makes each test distinct within the context of the contract as customers can exercise control over the test results upon delivery. Accordingly, the Company recognizes test processing revenue as individual test results are delivered to customers.

For certain contracts with pharmaceutical companies where the Company is developing a companion diagnostic test in addition to performing regular testing services, revenue is primarily recognized proportionally as services are performed and/or tests are delivered.

A performance obligation represents a promise in a contract to transfer a distinct good or service to a customer, which represents a unit of accounting in accordance with ASC 606. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance obligation satisfied once the Company has transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. A portion of the consideration should be allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The Company evaluates its contracts with laboratory partners and patients and identifies the performance obligations in those contracts, which are the delivery of the test results.

The total consideration which the Company expects to collect in exchange for the Company’s products is an estimate and may be fixed or variable. Consideration includes reimbursement from both patients and insurance carriers, adjusted for variable consideration related to disallowed cases, percent of patient responsibility collected, refunds and reserves, and is estimated using the most likely amount method. For insurance carriers and product types with similar reimbursement characteristics, the Company uses a portfolio of relevant historical data to estimate variable consideration and total collections for the Company’s products. The Company constrains the estimated variable consideration when it assesses it is probable that a significant reversal in the amount of cumulative revenue recognized may occur in future periods. The consideration expected from laboratory partners usually includes a fixed amount, but it can be variable depending on the volume of tests performed, and the Company determines the variable consideration using the expected value approach. For laboratory partners and patients, the Company allocates the total consideration to a single performance obligation, which is the delivery of the test results to the customers.

When assessing the total consideration expected to be received from insurance carriers and patients, a certain percentage of revenues is further constrained for estimated refunds.

The Company enters into contracts with insurance carriers with primarily payment terms related to tests provided to patients who have health insurance coverage. Insurance carriers are considered as third-party payers on behalf of the patients, and the patients are considered as the customers who receive genetic test services. Tests may be billed to insurance carriers, patients, or a combination of insurance carriers and patients. Further, the Company sells tests to a number of domestic and international laboratory partners and identifies the laboratory partners as customers provided that there is a test services agreement between the two parties.

The Company generally bills an insurance carrier, a laboratory partner or a patient upon delivery of test results. The Company also bills patients directly for out-of-pocket costs involving co-pays and deductibles that they are responsible for. The Company may or may not get reimbursed for the full amount billed. Further, the Company may not get reimbursed at all for tests performed if such tests are not covered under the insurance carrier’s reimbursement policies or the Company is not a qualified provider to the insurance carrier, or if the tests were not previously authorized.

Product revenue is recognized in an amount equal to the total consideration (as described above) expected to be received at a point in time when the test results are delivered. Approximately 90% of cash collections attributable to such product revenue occurs within nine months with the remaining collections generally taking an additionalsix months. During this time, management routinely reassesses its estimates of actual to expected cash collections, which are based on historical collection rates and adjusted for current information and trends. To the extent cash collections for tests delivered in prior periods are trending higher than expectations, the Company will increase revenue recognized when sufficient evidence is obtained to conclude the additional revenue will not result in a reversal of revenue in a future period. If cash collections for tests delivered in prior periods are trending below expectations, the Company will reduce revenue to the amount expected to be collected based on the latest information and expectations. Increases or decreases to the amount of cash expected to be collected for tests delivered in prior periods are recognized in product revenue with a corresponding impact to accounts receivable during the period such determination is made. During the three months ended June 30, 2024

and 2023, the Company increased revenue by a net of $39.9 million and $3.4 million, respectively, for collections related to tests delivered in prior periods that were fully collected (including an estimate of unapplied receipts). The increased revenue anddecreased net loss resulted in a corresponding decrease in loss per share by $0.32 and $0.03 for the three months ended June 30, 2024 and 2023, respectively. During the six months ended June 30, 2024, the Company increased revenue by a net of $73.7 million for collections related to tests delivered in prior periods that were fully collected (including an estimate of unapplied receipts). The increased revenue and decreasednet loss resulted in a corresponding decrease in loss per share by $0.60 for the six months ended June 30, 2024. During the six months ended June 30, 2023, the Company reduced revenue by a net of $5.8 million for a reduction in expected collections related to tests delivered in prior periods. The decreased revenue and increasednet loss resulted in a corresponding increase in loss per share by $0.05 for the six months ended June 30, 2023.

As of June 30, 2024, the Company had $16.6 million in cash receipts which had not yet been applied to specific accounts receivables primarily due to the disruption to Change Healthcare’s network that occurred in February 2024. The Company reviewed the historical unapplied payment trends. Based on the historical estimation, within the unapplied cash receipt of $16.6 million, the Company estimated approximately $1.3 million was related to tests delivered in prior periods that were fully collected. Additionally, as overpayments were not material in prior periods, the Company accounted for temporary unapplied balances as of June 30, 2024, as contra accounts receivable on the Balance Sheet. As of December 31, 2023, the unapplied accounts receivable balance was $1.3 million.

Product revenue is constrained for refunds estimated to be paid to insurance carriers. Certain refunds are recognized in accrued liabilities until they are either paid to the respective insurance carrier or it is determined the refund will not ultimately be paid, at which time the related accrual is reduced with a corresponding increase to revenue. During the three months ended June 30, 2024 and 2023, the reserves for refunds to insurance carriers were reduced and product revenue increased by $1.7 million and $0.8 million, respectively, for amounts the Company determined would not be refunded to insurance carriers. The increased revenue and corresponding decreased net loss resulted in a decreased loss per share by $0.01 for both the three months ended June 30, 2024 and 2023, respectively. During the six months ended June 30, 2024 and 2023, the reserves for refunds to insurance carriers were reduced and product revenue increased by $3.8 million and $6.5 million, respectively, for amounts the Company determined would not be refunded to insurance carriers. The increased revenue and corresponding decreased net loss resulted in a decreased loss per share by $0.03 and $0.06 for the six months ended June 30, 2024 and 2023, respectively.

In addition, certain other refunds are recognized as a reduction to accounts receivable until they are either paid to the respective insurance carrier or it is determined the refund will not ultimately be paid, at which time the related reserve is reduced with a corresponding increase to revenue. During the three months ended June 30, 2024, the reserves for refunds to insurance carriers were reduced and product revenue increased by $1.9 million for amounts the Company determined would not be refunded to insurance carriers. The increased revenue and corresponding decreasednet loss resulted in a decreased loss per share by $0.02 for the three months ended June 30, 2024. During the six months ended June 30, 2024, the reserves for refunds to insurance carriers were reduced and product revenue increased by $4.1 million for amounts the Company determined would not be refunded to insurance carriers. The increased revenue and decreasednet loss resulted in a decreased loss per share by $0.03 for the six months ended June 30, 2024. There was no such adjustment in the three and six months ended June 30, 2023.

Licensing and Other Revenues

The Company recognizes licensing revenues from its cloud-based distribution service offering, Constellation, by granting licenses to its licensees to use certain of the Company’s proprietary intellectual properties and cloud-based software and in vitro diagnostic (“IVD”) kits. The Company also recognizes revenues from its strategic collaboration agreements, such as those with BGI Genomics Co., Ltd. (“BGI Genomics”) and Foundation Medicine, Inc. (“Foundation Medicine”). The Company recognizes licensing and other revenues through agreements with pharmaceutical companies in support of potential clinical trials managed by the pharmaceutical companies.

Constellation

The laboratory partners with whom the Company enters into a licensing arrangement represent the licensees and are identified as customers. The licensees do not have the right to possess the Company’s software, but rather receive services through the cloud software. These arrangements often include: (i) the delivery of the services through the cloud software, (ii) the necessary support and training, and (iii) the IVD kits to be consumed as tests are processed. The Company does not consider the software as a service, the support or the training as being distinct in the context of such arrangements, and therefore they are combined as a single performance obligation. The software, support and training are delivered simultaneously to the licensees over the term of the arrangement.

The Company bills the majority of licensees, who process the tests in their laboratories, a fixed price for each test processed. Licensing revenues are recognized as the performance obligations are satisfied (i.e., upon the delivery of each test) and reported in licensing and other revenues in the Company’s statements of operations and comprehensive loss.

In February 2019, the Company entered into a License Agreement (the “BGI Genomics Agreement”) with BGI Genomics to develop, manufacture, and commercialize next generation sequencing-based genetic testing assays for clinical and commercial use. The BGI Genomics Agreement has a term often years and expires in February 2029. Pursuant to the BGI Genomics Agreement, the Company licensed its intellectual property to and provided development services for BGI Genomics. Following completion of development services, the Company began providing assay interpretation services over the term of the agreement.

According to the BGI Genomics Agreement, the Company is entitled to a total of $50.0 million, comprised of upfront technology license fees, prepaid royalties relating to future sales of licensed products and performance of assay interpretation services, and milestone payments. Due to uncertainties in achieving certain milestones, $6.0 million of the $50.0 million was constrained. A net of $44.0 million has been collected by the Company in cash, which includes $20.0 million in prepaid royalties.

The Company concluded that the license is not a distinct performance obligation as it does not have a stand-alone value to BGI Genomics apart from the related development services. Therefore, license and related development services, for each of the non-invasive prenatal tests (“NIPTs”) and Oncology products, representingtwo separate performance obligations, to which $24.0 million of transaction consideration was allocated. This performance obligation was fully satisfied in March 2023 and no further related amounts will be recognized as revenue.

As of December 31, 2023, the Company's performance obligation to provide ongoing NIPT assay interpretation services was removed. Therefore, the Company now has a single remaining performance obligation related to Oncology assay interpretation services, to which $20.0 million of transaction consideration was allocated and prepaid by BGI Genomics. During the six months ended June 30, 2023, the Company recognized $0.6 million related to oncology assay interpretation services, of which $0.2 million was recognized against deferred royalties. During the six months ended June 30, 2024, the Company did not record any material amounts related to oncology assay interpretation services. The Company currently has $18.9 million in deferred revenue as of June 30, 2024.

As required by the BGI Genomics Agreement, in June 2019 the Company prepaid $6.0 million to BGI Genomics for future sequencing services and $4.0 million for future sequencing equipment. These advance payments are for equipment and services to be received in future periods, which was assessed as a standalone transaction that did not reduce revenue, aggregated to $10.0 million and was originally recorded in long-term advances on the Company’s Consolidated Balance Sheet and will be periodically assessed for impairment. During both the three and six months ended June 30, 2024, $0.4 million in equipment and services was received. During the three and six months ended June 30, 2023, $1.0 million and $2.6 million, respectively, in equipment and services was received. As of June 30, 2024, the remaining advanced payments were $4.5 million, with $0.6 million recorded in prepaid expenses and other current assets and $3.8 million recorded in other assets.

Foundation Medicine, Inc.

In August 2019, the Company entered into a License and Collaboration Agreement (the “Foundation Medicine Agreement”) with Foundation Medicine to develop and commercialize personalized circulating tumor DNA monitoring assays, for use by biopharmaceutical and clinical customers who order Foundation Medicine’s FoundationOne CDx. The Company and Foundation Medicine will share the revenues generated from both biopharmaceutical and clinical customers in accordance with the terms of the Foundation Medicine Agreement. The Foundation Medicine Agreement has an initial term offive years, expiring in August 2024, with automatic renewals thereafter for successiveone-year terms, unless the Foundation Medicine Agreement is earlier terminated in accordance with its terms. The Company and Foundation Medicine have elected not to renew the agreement beyond the initial term.

Pursuant to the Foundation Medicine Agreement, the Company will provide development services that are required to customize its proprietary Signatera test to work with Foundation Medicine’s FoundationOne CDx in conjunction with granting the use of the Company’s intellectual property. Following completion of those development services, the Company is currently providing assay testing services over the term of the agreement. The intellectual property has been licensed to Foundation Medicine for the customized test. In addition, the Company is responsible for delivering clinical study plans in order to demonstrate efficacy of the customized test which commenced in the second quarter of 2021.

The Company is entitled to a total of $32.0 million, comprised of upfront technology license fees, prepaid royalties relating to future sales of licensed products and performance of assay interpretation services, and milestone payments. $7.7 million is constrained due to uncertainties in achieving certain milestones. A net of $24.3 million has been collected by the Company in cash, which includes $5.0 million of prepaid royalties.

The Company concluded that the license is not a distinct performance obligation as it does not have a stand-alone value to Foundation Medicine apart from the related development services. Therefore, license and related development services, for Oncology products, represent a single performance obligation, to which $19.3 million of transaction consideration was allocated. Of this amount, $0.2 million was recognized in the three months ended March 31, 2023. This performance obligation was fully satisfied in March 2023 and no further related amounts will be recognized as revenue.

Royalties related to assay interpretation services represent separate performance obligations for Oncology products, to which $5.0 million of transaction consideration was allocated and prepaid by Foundation Medicine. During the three and six months ended June 30, 2023, the Company recognized $0.1 million and $0.4 million, respectively, related to oncology assay interpretation services. During the three and six months ended June 30, 2024, the Company recognized $0.2 million related to oncology assay interpretation services. The Company currently has $3.0 million in deferred revenue related to this agreement as of June 30, 2024.

The following table presents total revenues by geographic area based on the location of the Company’s payers:

The following table summarizes the Company’s beginning and ending balances of accounts receivable and deferred revenues:

The following table summarizes the changes in the balance of deferred revenues during the six months ended June 30, 2024 and 2023:

During the six months ended June 30, 2024, revenue recognized that was included in the deferred revenue balance at the beginning of the period totaled $9.6 million. This balance consisted of approximately a net $0.1 million related to BGI Genomics and Foundation Medicine and $9.5 million related to genetic testing services. The current portion of deferred revenue includes $14.8 million from genetic testing services, $0.5 million from BGI Genomics, and $3.0 million from the Foundation Medicine Agreement as of June 30, 2024. The non-current portion of deferred revenue consists of $18.4 million from the BGI Genomics Agreement as of June 30, 2024.

4. Fair Value Measurements

The Company's financial assets and liabilities carried at fair value are comprised of investment assets that include money market and investments.

The fair value accounting guidance requires that assets and liabilities be carried at fair value and classified in one of the following three categories:

Level I: Quoted prices in active markets for identical assets and liabilities that the Company has the ability to access.

Level II: Observable market-based inputs or unobservable inputs that are corroborated by market data, such as quoted prices, interest rates, and yield curves; and

Level III: Inputs that are unobservable data points that are not corroborated by market data.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis

The following table represents the fair value hierarchy for the Company’s financial assets and financial liabilities measured at fair value on a recurring basis:

Fair Value of Short-Term and Long-Term Debt:

As of June 30, 2024 and December 31, 2023, the estimated fair value of the total principal outstanding and accrued interest of the Credit Line was $80.4 million, and were based upon observable Level 2 inputs, including the interest rate based on the 30-day Secured Overnight Financing Rate (“SOFR”) average, plus 0.5%. The estimated fair value approximates the carrying value due to the short term duration and variable interest rate.

As of June 30, 2024 and December 31, 2023, the estimated fair value of the Convertible Notes was $800.7 million and $491.8 million, respectively, based upon observable, Level 2 inputs, including pricing information from recent trades of the Convertible Notes. See Note 10,Debt, for additional details and carrying value.

5. Financial Instruments

The Company elected to invest a portion of its cash assets in conservative, income earning, and liquid investments. Cash, cash equivalents, restricted cash and investments, which are classified as available-for-sale securities, consisted of the following:

The Company invests in U.S. Treasuries, U.S. agency and high-quality municipal bonds which mature at par value and are all paying their coupons on schedule. The Company has therefore concluded an allowance for expected credit losses of its investments was not necessary and will continue to recognize unrealized gains and losses in other comprehensive income (loss). During the six months ended June 30, 2024, the Company didnot sell any investments. The Company uses the specific investment identification method to calculate realized gains and losses and amounts reclassified out of other comprehensive income (loss) to net loss. As of June 30, 2024, the Company had 15 investments in an unrealized loss position in its portfolio. Gross unrealized losses were not material as of June 30, 2024. Gross unrealized losses were primarily due to declines in the value of fixed rate instruments as interest rates in the broader market increased, and were not indictive of a decline in the credit worthiness of the underlying issuer, and as such, the Company didnot record a credit loss reserve as of June 30, 2024.

The following table presents debt securities available-for-sale that were in an unrealized loss position as of June 30, 2024, aggregated by major security type in a continuous loss position.

The following table summarizes the Company’s portfolio of available-for-sale securities by contractual maturity as of June 30, 2024:

6. Balance Sheet Components

Allowance for doubtful accounts

The following is a roll-forward of the allowances for doubtful accounts related to trade accounts receivable for the three and six months ended June 30, 2024 and 2023:

Property and Equipment, net

The Company’s property and equipment consisted of the following:

The Company’s long-lived assets are located in the United States.

During the six months ended June 30, 2024, the increase in net property and equipment was due to expansion projects and purchases of new equipment for the Company’s laboratories located in Texas and California to expand testing capabilities, offset by depreciation expense of $13.3 million recorded in the six months ended June 30, 2024. Depreciation expense of $10.2 million was recorded in the six months ended June 30, 2023. The Company didnot incur any impairment charges during the six months ended June 30, 2024 or 2023.

Other Accrued Liabilities

The Company’s other accrued liabilities consisted of the following:

Reserves for refunds to insurance carriers include overpayments from and amounts to be refunded to insurance carriers, and additional amounts that the Company estimates for potential refund requests during the period. When the Company releases these previously accrued amounts, they are recognized as product revenues in the condensed statements of operations and comprehensive loss.

The following table summarizes the reserve balance and activities for refunds to insurance carriers for the six months ending June 30, 2024 and 2023:

As of June 30, 2024, the Company had $13.9 million in short term advances obtained as a result of the disruption to Change Healthcare’s network in February 2024 which are due and payable within ten days of demand.

7. Leases

Operating Leases

In September 2015, the Company entered into a long-term lease agreement for laboratory and office space totaling approximately 94,000 square feet in Austin, Texas. The original lease term was 132 months beginning in December 2015 and expiring in November 2026 with monthly payments beginning in December 2016. In December 2021, the Company entered into an amendment of the Austin lease agreement which extended the lease of the current premises through March 2033. The amendment also includestwo additional office spaces (the “First Expansion Premises” and the “Second

Expansion Premises”). The First Expansion Premises consists of 32,500 rentable square feet and commenced in February 2022. The Second Expansion Premises consists of 65,222 rentable square feet and commenced in September 2022. The terms of the First and Second Expansion Premises expire in March 2033.

In October 2016, the Company entered into a lease directly with its landlord for laboratory and office spaces at its facilities located in San Carlos, California. The Company currently occupies approximately 136,000 square feet comprised oftwo office spaces (the “First Space” and the “Second Space”). The First Space covers approximately 88,000 square feet, and the Second Space totals approximately 48,000 square feet. In January 2021, the Company entered into an amendment of the lease to extend the term for 48 months to October 2027. The combined annual rent for the First Space and Second Space is $9.3 million which commenced in October 2023.

The Company entered into a lease agreement commencing June 2018 for its cord blood tissue storage facility in Tukwila, Washington that covers approximately 10,000 square feet. The lease term is 62 months and expired in July 2023. The Company had the option to extend this lease forfive years, and the fair market rent upon renewal was not determinable. However, since the Company sold its business related to cord blood and tissue storage in September 2019, the Company has subleased the facility and did not exercise its option to renew the facility upon expiration.

The Company entered into a lease agreement in November 2020 to lease 11,395 square feet of space located in South San Francisco, California over a 36-month term. The premises are used for general office, laboratory and research use. The annual lease payment starts at $0.9 million and escalates annually after commencing in December 2021. In December 2022, the Company exercised the renewal option of the South San Francisco lease agreement. In January 2023, the Company entered in an amendment to extend the lease term of the South San Francisco premises bythree years, through November 2026.

The Company entered into a lease agreement in September 2023 to lease 16,319 square feet of space located in Pleasanton, California over a 60-month term. The premises are used for laboratory and research use and commenced in December 2023. The annual lease payment starts at $0.5 million and escalates annually.

As part of the IPR&D asset acquisition in September 2021, the Company inherited a 24-month lease for 7,107 square feet of laboratory space in Canada. The annual lease payment started at $0.2 million and expired in August 2023.

The Company has also historically entered into leases of individual workspaces and storage spaces at various locations on both a month-to-month basis without an established lease term, and more recently for certain locations, has committed to terms approximatingone tofive years. For the facilities without a committed lease term, the Company has elected to not recognize them as right-of-use assets on the condensed consolidated balance sheets as they are all considered short-term leases. For individual workspaces where the committed lease term exceeds one year, the Company has recorded a right-of-use asset on the condensed consolidated balance sheets.

For the six months ended June 30, 2024, the Company had $0.6 million in noncash operating activities related to additional right-of-use assets accounted from a new lease and extending existing leases under ASC, Topic 842, Leases

(“ASC 842”). For the six months ended June 30, 2023, the Company didnot have any noncash operating activities related to additional right-of-use assets.

The operating lease right-of-use assets are classified as noncurrent assets in the balance sheet. The corresponding lease liabilities are separated into current and long-term portions as follows:

The initial recognition of the operating lease liabilities was measured as the present value of the future minimum lease payments using a discount rate determined as of January 1, 2019. The operating right-of-use assets was calculated as the operating lease liabilities discounted at the present value, less the amount of unamortized tenant improvement allowance and deferred rent. The discount rate used was the Company’s incremental borrowing rate given that the implicit rate to each lease was not readily determinable. In accordance with ASC 842, the incremental borrowing rate was estimated as the annual percentage yield resulting from a corporate debt financing over a loan term approximating the remaining term of each lease, with the effect of certain credit risk rating. As of June 30, 2024, the weighted-average remaining lease term was 6.30 years and the weighted-average discount rate was 6.8%.

The Company continues to recognize lease expense on a straight-line basis. The lease expense includes the amortization of the right-of-use assets with the associated interest component estimated by applying the effective interest method. For the three months ended June 30, 2024 and 2023, total lease expense of $3.6 million and $3.7 million was recognized in the condensed statements of operations and comprehensive loss, respectively. For the six months ended June 30, 2024 and 2023, total lease expense of $7.2 million and $7.5 million was recognized in the condensed statements of operations and comprehensive loss, respectively. Cash paid for amounts in the measurement of operating lease liabilities totaled $4.1 million and $3.0 million for the three months ended June 30, 2024 and 2023, respectively. Cash paid for amounts in the measurement of operating lease liabilities totaled $8.3 million and $5.2 million for the six months ended June 30, 2024 and 2023, respectively.

The present value of the future annual minimum lease payments under all non-cancellable operating leases as of June 30, 2024 are as follows:

8. Commitments and Contingencies

Legal Proceedings

The Company is involved in legal matters, including investigations, subpoenas, demands, disputes, litigation, requests for information, and other regulatory or administrative actions or proceedings, including those with respect to intellectual property, testing and test performance, billing, reimbursement, marketing, short seller and media allegations, employment, and other matters.

The Company is responding to ongoing regulatory and governmental investigations, subpoenas and inquiries, and contesting its current legal matters, but cannot provide any assurance as to the ultimate outcome with respect to any of the foregoing. There are many uncertainties associated with these matters. Such matters may cause the Company to incur costly litigation and/or substantial settlement charges, divert management attention, result in adverse judgments, fines, penalties, injunctions or other relief, and may result in loss of customer or investor confidence regardless of their merit or ultimate outcome. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of the foregoing were to occur, the Company’s business, financial condition, results of operations, cash flows, prospects, or stock price could be adversely affected.

The Company assesses legal contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. When evaluating legal contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation or other matters may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability. Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. During the periods presented, the Company does not believe there are such matters that will have a material effect on its financial condition.

Intellectual Property Litigation Matters.

The Company has been involved intwo patent litigations against CareDx, Inc. (“CareDx”) in the United States District Court for the District of Delaware (“CareDx Patent Cases”). In the first CareDx Patent Case, CareDx alleged, in a complaint filed jointly with the Board of Trustees of the Leland Stanford Junior University in March 2019 and amended in March 2020, that the Company infringed three patents (the “CareDx Patents”). The complaint sought unspecified damages and injunctive relief. In September 2021, the Court granted the Company’s motion for summary judgment, finding allthree CareDx Patents invalid. This finding was affirmed on appeal by the United States Court of Appeals for the Federal Circuit. CareDx’s petition for rehearing by the Federal Circuit, and its subsequent petition for certiorari to the United States Supreme Court, were both denied. In the second CareDx Patent Case, the Company alleged, in suits filed in January 2020 and May 2022, infringement by CareDx of certain of the Company’s patents, seeking unspecified damages and injunctive relief. In January 2024, after trial, the jury returned a verdict in favor of the Company, finding both asserted patents valid andone patent infringed by CareDx. The jury awarded damages to the Company for lost profits and past royalties totaling $96.3 million.

In January 2020, the Company filed suit against ArcherDX, Inc. (“ArcherDX”) in the United States District Court for the District of Delaware. In January 2021, the Company named an additional Archer DX entity, ArcherDx LLC, and Invitae as defendants. The Company alleged, among other things, that certain ArcherDX products, including the Personalized Cancer Monitoring (“PCM”) test, infringed three of the Company’s patents (the “ArcherDX Case”) and sought unspecified monetary damages and injunctive relief. Following a jury trial in May 2023 and a bench trial in June 2023, allthree asserted patents were found to be valid and infringed by ArcherDX and Invitae, and the jury awarded damages totaling $19.35 million to the Company. In November 2023, the Court granted in part the Company’s motion for a permanent injunction against the PCM test, which the defendants have appealed. In February 2024, Invitae and ArcherDX filed a voluntary Chapter 11 petition in the U.S. Bankruptcy Court for the District of New Jersey, resulting in an automatic bankruptcy stay in the case.

The Company is the subject of a lawsuit filed against it by Ravgen, Inc. (“Ravgen”) in June 2020 in the United States District Court for the Western District of Texas, alleging infringement oftwo Ravgen patents and seeking monetary damages and injunctive relief. In January 2024, after trial, the jury returned a verdict of non-willful infringement by the Company and found damages of $57 million. The Company intends to appeal certain of the rulings. In addition, various parties, including the Company, have filed petitions challenging the validity of the asserted patents with the United States Patent and Trademark Office, all of which were instituted for review, and some of which were decided in favor of upholding the challenged claims. The petitions filed by the Company and certain others remain pending.

In October 2020, the Company filed suit against Genosity Inc. (“Genosity”), in the United States District Court for the District of Delaware, alleging that various Genosity products infringeone of the Company’s patents and seeking unspecified monetary damages and injunctive relief. The case has been stayed pending the entry of a final judgment in the ArcherDX Case, in which the subject patent is also asserted. In February 2024, Genosity filed a voluntary Chapter 11 petiion in the U.S. Bankruptcy Court for the District of New Jersey.

The Company is the subject of lawsuits filed against it by Invitae in the United States District Court of the District of Delaware alleging, in complaints filed in May and November of 2021, infringement of three patents and seeking monetary damages and injunctive relief. The parties have filed cross-motions for summary judgment, which motions are currently pending before the Court. In February 2024, subsequent to Invitae’s voluntary Chapter 11 petition described above, the Court granted Invitae’s request to continue the trial, which is now scheduled for September 2025.

The Company filed suits against Inivata, Inc. and Inivata Ltd. (collectively “Inivata”) in the United States District Court for the District of Delaware in January 2021 and December 2022, alleging that certain of Inivata’s oncology products infringe certain of the Company’s patents and seeking unspecified monetary damages and injunctive relief. Thetwo suits have been consolidated. Inivata has filed a motion to dismiss the Company’s complaint with respect toone patent, which motion is currently pending before the Court. In March 2024, the Court stayed the case in light of the Company’s case against NeoGenomics Laboratories, Inc. (“NeoGenomics”), which acquired Inivata in 2021, discussed below.

In July 2023, the Company filed suit against NeoGenomics in the United States District Court for the Middle District of North Carolina (the “District Court”), alleging infringement of certain Natera patents by NeoGenomics’ commercialization of the RaDaR test. The complaint seeks monetary damages and injunctive relief. In December 2023, the Court denied NeoGenomics’ motion to dismiss the complaint, and granted the Company’s motion for preliminary injunction. The injunction went into effect as of January 12, 2024. NeoGenomics filed a motion to modify and stay the injunction, which was denied by the District Court and affirmed on appeal in July 2024 by the Federal Circuit Court of Appeals. NeoGenomics has also filed petitions challenging the validity of both of the asserted patents with the United States Patent and Trademark Office. One of the petitions has been denied.

Other Litigation Matters.

CareDx filed suit against the Company in April 2019 in the United States District Court for the District of Delaware, alleging false advertising, and related claims based on statements describing studies that concern the Company’s technology and CareDx’s technology, seeking unspecified damages and injunctive relief. The Company filed a counterclaim against CareDx in the United States District Court for the District of Delaware, alleging false advertising, unfair competition and deceptive trade practices and seeking unspecified damages and injunctive relief. In March 2022, after trial, the jury returned a verdict that the Company was liable to CareDx and found damages of $44.9 million. The jury also returned a verdict against CareDx, finding that CareDx had engaged in false advertising. In July 2023, the Court granted in part the Company’s motion for judgment as a matter of law requesting that the Court set aside the portions of the jury verdict adverse to the Company, ruling that CareDx is not entitled to any damages. The jury verdict of false advertising by CareDx remains in place. Both parties are appealing.

In May 2021, Guardant. Inc. (“Guardant”) filed suit against the Company in the United States District Court of the Northern District of California alleging false advertising and related claims and seeking unspecified damages and injunctive relief. Also in May 2021, the Company filed suit against Guardant in the Western District of Texas, alleging false advertising and related claims. The Company has voluntarily dismissed its Texas suit against Guardant and has

asserted the claims from the Texas action as counterclaims in the California action, seeking unspecified damages and injunctive relief. In August 2021, Guardant moved to dismiss the Company’s counterclaims, which motion was denied in all material respects. Both parties filed cross-motions for summary judgment, which were granted in part and denied in part. Trial is currently scheduled for November 2024.

In November 2021, a purported class action lawsuit was filed against the Company in the United States District Court for the Northern District of California, by a patient alleging various causes of action relating to the Company’s patient billing and seeks, among other relief, class certification, injunctive relief, restitution and/or disgorgement, attorneys’ fees, and costs. In May 2023, the Court granted the Company’s motion to dismiss the lawsuit, and the case was dismissed without prejudice. In July 2023, the plaintiff filed analogous claims in the Superior Court of California, County of San Mateo, and subsequently filed an amended claim with an additional plaintiff. Based on the additional plaintiff, the case was transferred back to the United States District Court for the Northern District of California. The parties subsequently agreed that claims brought by the original plaintiff be remanded back to the Superior Court of California, County of San Mateo, and that the action be stayed pending the outcome of the action in the United States District Court for the Northern District of California.

In February 2022, two purported class action lawsuits were filed against the Company in the United States District Court for the Northern District of California. Each suit was filed by an individual patient alleging various causes of action related to the marketing of Panorama and seeking, among other relief, class certification, monetary damages, attorneys’ fees, and costs. These matters have been consolidated. The Company filed a motion to dismiss the consolidated lawsuit, which resulted in the plaintiffs filing an amended complaint in April 2023.

In March 2022, a purported class action lawsuit was filed against the Company and certain of its management in the Supreme Court of the State of New York, County of New York, asserting claims under Sections 11, 12, and 15 of the Securities Act of 1933. The complaint alleges, among other things, that the Company failed to disclose certain information regarding its Panorama test. The complaint seeks, among other relief, monetary damages, attorneys’ fees, and costs. This matter has been dismissed and the claims raised in this matter have been included in the lawsuit discussed below.

A purported class action lawsuit was filed against the Company and certain of its management in the United States District Court for the Western District of Texas, asserting claims under Sections 10(b) and 20(a) of the Securities Act of 1934 and Rule 10b-5 thereunder. The complaint, filed in April 2022 and amended in October 2022 (to include, among others, the claims raised in the lawsuit discussed in the preceding paragraph), alleges, among other things, that the management defendants made materially false or misleading statements, and/or omitted material information that was required to be disclosed, about certain of the Company’s products and operations. The complaint seeks, among other relief, monetary damages, attorneys’ fees, and costs. The Company filed a motion to dismiss this lawsuit, which was granted in part and denied in part.

In each of October 2023 and January 2024, shareholder derivative complaints were filed in the United States District Court for the Western District of Texas and the United States District Court for the District of Delaware, respectively, against the Company as nominal defendant and certain of the Company’s management. Each complaint alleges, among other things, that the management defendants made materially false or misleading statements, and/or omitted material information that was required to be disclosed, about certain of the Company’s products and operations. Each complaint seeks, among other relief, monetary damages, attorneys’ fees, and costs.

Director and Officer Indemnifications

As permitted under Delaware law, and as set forth in the Company’s Amended and Restated Certificate of Incorporation and its Amended and Restated Bylaws, the Company indemnifies its directors, executive officers, other officers, employees and other agents for certain events or occurrences that may arise while in such capacity. The maximum potential future payments the Company could be required to make under this indemnification is unlimited; however, the Company has insurance policies that may limit its exposure and may enable it to recover a portion of any future amounts paid. Assuming the applicability of coverage, the willingness of the insurer to assume coverage, and subject to certain retention, loss limits and other policy provisions, the Company believes any obligations under this indemnification would

not be material, other than standard retention amounts for securities related claims. However, no assurances can be given that the covering insurers will not attempt to dispute the validity, applicability, or amount of coverage without expensive litigation against these insurers, in which case the Company may incur substantial liabilities as a result of these indemnification obligations.

Third-Party Payer Reimbursement Audits

From time to time, the Company receives recoupment requests from third-party payers for alleged overpayments. The Company disagrees with the contentions of pending requests and/or has recorded an estimated reserve for the alleged overpayments if probable and estimable.

Contractual Commitments

The following table sets forth the Company’s material contractual commitments as of June 30, 2024:

In September 2015, the Company entered into a credit line with UBS (the “Credit Line”) providing for a $50.0 million revolving line of credit which was fully drawn down in 2016. The Credit Line was amended in July 2017 and bears interest at 30-day LIBOR plus 1.10%. The interest rate was subsequently changed to the 30-day SOFR average, plus 1.21%. The SOFR rate is variable. The interest rate as of June 30, 2024 was 5.84%. The Credit Line was subsequently increased from $50.0 million to $150.0 million in 2020. In November 2022, the Company drew down $30.0 million from the $100.0 million available from the Credit Line. The Credit Line is secured by a first priority lien and security interest in the Company’s money market and marketable securities held in its managed investment account with UBS. The Company is required to maintain a minimum of at least $150.0 million in its UBS accounts as collateral. UBS has the right to demand full or partial payment of the Credit Line obligations and terminate the Credit Line, in its discretion and without cause, at any time. In June 2023, the Credit Line decreased from $150.0 million to $100.0 million. In October 2023, the interest rate for the Credit Line was subsequently changed to the 30-day SOFR average, plus 0.5%. As of June 30, 2024, the Company has drawn down a total of $80.0 million and there is $20.0 million remaining and available on the Credit Line.

In April 2020, the Company issued $287.5 million aggregate principal amount of Convertible Notes due 2027 in a private placement offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 2.25% per year, payable in cash semi-annually. The Convertible Notes mature in May 2027, unless earlier converted, repurchased or redeemed in accordance with their terms. Upon conversion, the Convertible Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election.

The Company received net proceeds from the Convertible Notes of $278.3 million, after deducting the initial purchasers’ discounts and debt issuance costs. In 2020, the Company used approximately $79.2 million of the net proceeds from the Convertible Notes offering to repay its obligations under its credit agreement with OrbiMed Royalty Opportunities II, LP.

The holders of the Convertible Notes may convert all or a portion of their Convertible Notes at their option at any time prior to the close of business on the business day immediately preceding February 1, 2027 in multiples of $1,000 principal amount, under any the following circumstances:

The first circumstance has been met as of June 30, 2024. However, there were no conversions for the period ending June 30, 2024.

The Convertible Notes are convertible into shares of the Company’s common stock, par value $0.0001 per share, at an initial conversion rate of 25.7785 shares of common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $38.79 per share of common stock, convertible to 7,411,704 shares of common stock. The conversion rate and corresponding conversion price are subject to adjustment upon the occurrence of certain events but will not be adjusted for any accrued or unpaid interest. The holders of the Convertible Notes who redeem their Convertible Notes in connection with a make-whole fundamental change are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change, the holders of the Convertible Notes may require the Company to repurchase for cash all or a portion of their Convertible Notes at a price equal to 100% of the principal amount, plus any accrued and unpaid interest.

The Company may not redeem the Convertible Notes prior to May 2024, and no sinking fund is provided for the Convertible Notes. The Company may redeem for cash all or any portion of the Convertible Notes, at the Company’s option, on or after May 2024, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on the trading day immediately preceding the date on which the Company provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the Convertible Notes to be redeemed plus accrued and unpaid interest.

Upon adoption of ASU 2020-06,Debt with Conversion and Other Options (Subtopic 470-20) and Derivative and Heading-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in Entity’s Own Equity, the Company allocated all of the debt discount to long-term debt. The debt discount is amortized to interest expense using the effective interest method, computed to be 2.72%, over the life of the Convertible Notes or approximately itsseven-year term. The outstanding Convertible Notes balances as of June 30, 2024 and December 31, 2023 are summarized in the following table:

The following tables present total interest expense recognized related to the Convertible Notes during the three and six months ended June 30, 2024 and 2023:

11. Income Taxes

During the three months ended June 30, 2024 and 2023, the Company recorded total income tax expense (benefit) of approximately $892,000 and ($282,000), respectively. During the six months ended June 30, 2024 and 2023, the Company recorded total income tax expense (benefit) of approximately $1,320,000 and ($122,000), respectively. The income tax expense is primarily attributable to state income tax and foreign income tax. Due to the Company’s history of cumulative operating losses, the Company concluded that, after considering all the available objective evidence, it is not more likely than not that all of the Company’s net deferred tax assets will be realized. Accordingly, all of the Company’s deferred tax assets, which includes net operating loss carryforwards and tax credits related primarily to research and development, continue to be subjected to a full valuation allowance as of June 30, 2024. The Company will continue to maintain a full valuation allowance until there is sufficient evidence to support recoverability of its deferred tax assets.

Interest and/or penalties related to income tax matters are recognized as a component of income tax expense. As of June 30, 2024 and December 31, 2023, there wereno accrued interest and penalties related to uncertain tax positions.

12. Net Loss per Share

The Convertible Notes are convertible by the holders as of June 30, 2024. Upon conversion, the Company has the option to pay cash, issue shares of common stock, or any combination thereof for the aggregate amount due upon conversion. If converted, the fair value of the shares issued to settle the Convertible Notes would exceed the Convertible Note principle by $504.2 million based on the closing price of the Company’s common stock as of June 30, 2024. Since the Company is in a net loss position in the periods presented, the shares which would be issued upon conversion of the Convertible Notes are excluded from the net loss per share calculation as it would have an antidilutive effect. As such, the 7.4 million shares underlying the conversion option of the Convertible Notes have been excluded from the calculation of diluted earnings per share. If converted, the Company does not intend to settle the obligation in cash.

The following table shows total outstanding potentially dilutive shares excluded from the computation of diluted loss per share as their effect would be anti-dilutive, as of June 30, 2024 and 2023:

13. Subsequent Events

On July 19, 2024, the Company elected to exercise its optional redemption right to redeem all $287.5 million aggregate principal amount of its outstanding 2.25% Convertible Notes due 2027 and instructed Wilmington Trust, National Association, as trustee under the Convertible Notes Indenture (the “Indenture Agreement”) governing the Convertible Notes, to issue a redemption notice to registered holders of the Convertible Notes. The date fixed for the

redemption of the Convertible Notes is October 11, 2024 (the “Redemption Date”). The redemption price for the Convertible Notes is equal to 100% of the principal amount of the Convertible Notes to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date. The Company elected physical settlement with the Company’s shares of common stock as the settlement method to apply to all conversions of the Convertible Notes. All terms and conditions associated with physical settlement are noted within the terms of the original Indenture Agreement.The conversion rate for holders who convert their Convertible Notes in connection with the Company’s election to redeem the Convertible Notes will be increased by 0.4284 additional shares pursuant to the Indenture Agreement. Based on the conversion terms of the Convertible Notes and the market price of its common stock, the Company expects that substantially all outstanding Convertible Notes will be converted into shares of its common stock prior to the Redemption Date. Should all holders elect to convert their Convertible Notes, approximately 7,534,000 shares of common stock would be issued for settlement.

In July 2024, the Company entered into an amendment of the San Carlos lease to extend the term for 60 months to October 2032. The annual rent will be approximately $10.6 million when the extension commences in October 2027.
