Natera, Inc.

Notes to Unaudited Interim Condensed Consolidated Financial Statements

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’s technology has been proven clinically and commercially in the women’s health space, in which it 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.  The Company is now translating its success in women’s health and applying its core technology to the oncology market, in which it is commercializing a personalized blood-based DNA test to detect molecular residual disease and monitor disease recurrence, as well as to the organ health market, initially with a test to assess kidney transplants for rejection. The Company operates laboratories in Austin, Texas and San Carlos, California certified under the Clinical Laboratory Improvement Amendments ("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 operates one 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 ("NIPT") 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 ("HCS") to determine carrier status for a large number of severe genetic diseases that could be passed on to the carrier’s children; Signatera molecular residual disease (“MRD”) test, which detects circulating tumor DNA in patients previously diagnosed with cancer to assess molecular residual disease and monitor for recurrence; and Prospera, to assess organ transplant rejection. All testing is available principally in the United States. The Company does not conduct animal testing. 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 nine months ended September 30, 2023, 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, 2022 (filed on March 1, 2023).

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 nine months ended September 30, 2023, 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, 2022 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, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2023.

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 and negative operating cash flows for the near future. The Company had a net loss of $356.8 million for the nine months ended September 30, 2023 and an accumulated deficit of $2.3 billion as of September 30, 2023. As of September 30, 2023, the Company had $668.7 million in cash, cash equivalents, and restricted cash, $267.8 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”). As of September 30, 2023, 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. 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 develop and commercialize future products and invest in the growth of its business and, consequently, will need to generate additional revenues to achieve future profitability and will 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 at all, 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 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 ASU 2017-01. 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 Natera common shares, 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 will be revalued at each reporting date and amount of compensation expense will be 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 Natera common stock.

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. In November 2022, the Company completed an underwritten equity offering and sold 13,144,500 shares of its common stock at a price of $35 per share to the public. Before estimated offering expenses of $0.5 million, the Company received proceeds of approximately $433.2 million net of the underwriting discount.

11

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 November 8, 2023.

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, average selling price expected to be received from payors, the discount rate impacting the operating right-of-use assets and the associated lease liabilities, the average useful life for property and equipment, 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. 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.

Revenue

The total consideration which the Company expects to be entitled to receive from patients and insurance carriers in exchange for the Company's products is a significant estimate determined by calculating the average selling price based on the contractual pricing agreed to with each insurance carrier for each test (CPT code) performed adjusted for variable consideration related to historical percent of cases allowed, historical percent of patient responsibility collected, and historical percent of contract price collected from insurance carriers. The Company uses the expected-value approach of estimating variable consideration.  The Company also considers recent 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 with similar reimbursement characteristics, the Company uses a portfolio approach to estimate the effects of variable consideration. The Company also applies a constraint to the estimated variable consideration when it assesses 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.

Allowance for doubtful accounts

The allowance for doubtful accounts for trade accounts receivable is based on the Company’s assessment of the collectability of accounts related to our 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 the three and nine months ended September 30, 2023 and 2022. The Company currently does not have an incremental 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.

12

Inventory

Inventory is recorded at the lower of cost or net realizable value, determined on a first-in, first-out basis. 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.

Investments and financial instruments

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.  

Other accrued liabilities

The Company's uses estimates, judgments, and assumptions in several areas including, but not limited to, estimates of progress to date for certain contracts with vendors, liabilities related to clinical trials, payroll and related expenses, marketing liabilities, reserves associated with insurance and general overpayments, tax-related liabilities, and other operating expenses. Estimates consist of historical trends, analytical procedures, review of supporting documentation, inquiries with supply partners and vendors, and other relevant assumptions. Although the Company believes its estimates, assumptions, and judgment are reasonable, they are based upon information presently available and are subject to change.

Credit Losses

Appropriate provision has been made for lifetime expected credit losses in accordance with ASC Topic 326-20, Financial Instruments—Credit Losses (“Topic 326”), for trade receivables and available-for-sale debt securities. The Company’s estimate of expected credit losses includes consideration of past events, current conditions, and forecasts of future economic conditions. The Company currently does not have a credit loss reserve against accounts receivable for insurance and patient payors due to the average selling price calculations which incorporate these risks as net receivables are recorded.  

Available-for-sale debt securities. The amended guidance from ASU 2016-13 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.

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-

13

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.

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, which represents 5.25% of MyOme on a fully diluted basis. The Company does not hold a seat on MyOme’s board of directors. The Company’s investment in MyOme is recorded at cost and no impairment was identified as of September 30, 2023. The following are the Company’s related persons and the basis of each such related person’s relationship with MyOme:

● Matthew Rabinowitz, the Company’s executive chairman and co-founder, is the chairman of the board and founder of MyOme, and a beneficial holder of approximately 28.6% of the outstanding shares of MyOme on a fully dilutive basis;

● Jonathan Sheena, the Company’s co-founder and a member of the Company’s board of directors, is a stockholder and a member of the board of directors of Myome;

● Daniel Rabinowitz, the Company’s Secretary and Chief Legal Officer, is a stockholder of Myome; and

● Roelof Botha, the Lead Independent Director of the Company’s board of directors, is a managing member of Sequoia Capital. Certain funds affiliated with Sequoia Capital also participated in MyOme’s series B financing.

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.

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).

Risk and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash, cash equivalents, 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.

The Company performs evaluations of financial conditions for insurance carriers, patients, clinics and laboratory partners and generally does not require collateral to support credit sales. For the three and nine months ended September 30, 2023, and 2022, there were no payors or customers exceeding 10% of total revenues on an individual basis. As of September 30, 2023 and December 31, 2022, there were no payors or customers with an outstanding balance exceeding 10% of net accounts receivable. 

14

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.

	Three months ended				Nine months ended
	September 30,				September 30,
	2023		2022		2023		2022
	(in thousands)				(in thousands)
Beginning balance	$	(9,203)	$	(16,397)	$	(16,362)	$	(2,287)
Net unrealized gain (loss) on available-for-sale securities, net of tax and foreign currency translation adjustment		3,807		(3,212)		10,966		(17,322)
Ending balance	$	(5,396)	$	(19,609)	$	(5,396)	$	(19,609)

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 losses was not necessary.

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. The Company does not expect adoption of this standard to have a material 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 from contracts with insurance carriers, laboratory partners and patients in connection with sales primarily related to prenatal genetic tests. The Company enters into contracts with insurance carriers with primarily payment terms related to tests provided to the 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.

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

15

pharmaceutical companies are identified as customers. Such arrangements generally involve performing whole exome sequencing (“WES”) services and the testing of patient samples to detect cancer mutations using its Signatera test. Each test is billable to customers 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. The Company allocates the contract price to each test using the stand-alone selling price for each service and recognizes the test processing revenue as individual test results are delivered to customers.

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 insurance carriers, 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, discounts, refunds and doubtful accounts, and is estimated using the expected value approach. For insurance carriers 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 insurance carriers, 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 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. Tests billed to insurance carriers and directly to patients usually takes an average of 18 months to fully collect the amounts estimated at delivery, and for tests billed to laboratory distribution partners, the average collection cycle takes approximately two to three months. At times, 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. Collection of cash attributable to such product revenue takes an average of 18 months to fully collect the amounts estimated at delivery and 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 September 30, 2023 and 2022, the Company increased revenue by a net of $2.2 million and $5.9 million, respectively, for tests delivered in prior periods that were fully collected, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by

16

$0.02 and $0.06, respectively. During the nine months ended September 30, 2023, the Company reduced revenue by a net of $3.7 million for tests delivered in prior periods, which decreased revenue and increased net loss by a corresponding amount and increased loss per share by $0.03. During the nine months ended September 30, 2022, the Company increased revenue by a net of $16.5 million for tests delivered in prior periods, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by $0.17.

Product revenue is constrained via refunds estimated to be paid to insurance carriers. Such 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 September 30, 2023 and 2022, the reserves for refunds to insurance carriers were reduced and product revenue increased by $1.2 million and $1.6 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 and $0.02 for the three months ended September 30, 2023 and 2022, respectively. During the nine months ended September 30, 2023 and 2022, the reserves for refunds to insurance carriers were reduced and product revenue increased by $7.7 million and $4.0 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 $0.07 and $0.04 for the nine months ended September 30, 2023 and 2022, respectively.

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 IVD kits. The Company also recognizes revenues from its strategic collaboration agreements, such as those with BGI Genomics Co., Ltd. and Foundation Medicine, Inc. The Company recognizes licensing revenue 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.

BGI Genomics

In February 2019, the Company entered into a License Agreement (the “BGI Genomics Agreement”) with BGI Genomics to develop, manufacture, and commercialize NGS-based genetic testing assays for clinical and commercial use. The BGI Genomics Agreement has a term of ten years and expires in February 2029. Pursuant to the BGI Genomics Agreement, the Company licensed its intellectual property to and will provide development services for BGI. Following completion of development services, the Company will provide assay interpretation services over the term of the agreement. Revenue associated with these performance obligations was recognized over time using the input method, based on costs incurred to perform the development services, since the level of costs incurred over time best reflect the transfer of development services. Revenue associated with the assay interpretation services will be recognized upon delivery of these services. Funds received in advance are recorded as deferred revenue and will be recognized as the related services are delivered.

17

In accordance with ASC 340-40, any incremental costs incurred to obtain a contract with a customer are required to be capitalized and amortized over the period in which the goods and services are transferred to the customer. The incremental costs incurred in connection with the BGI Genomics arrangement are not material on an accumulated basis and therefore have not been capitalized but have been expensed as incurred.

The initial transaction price was primarily comprised of license and milestone fees. 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. Certain milestone and license fees were constrained and not included in the transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The allocation of the transaction price was performed based on standalone selling prices, which are based on estimated amounts that the Company would charge for a performance obligation if it were sold separately.

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 NIPT and Oncology products, representing two separate performance obligations, to which $24.0 million of transaction consideration was allocated. Of this amount, $0.1 million and $7.3 million were recognized in the nine months ended September 30, 2023 and 2022, respectively. This performance obligation was fully satisfied in March 2023 and no further related amounts will be recognized as revenue.

As of September 30, 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 nine months ended September 30, 2023, the Company recognized $1.1 million related to oncology assay interpretation services, of which $0.7 million was recognized against deferred royalties. None was recognized in 2022. The Company currently has $19.3 million in deferred revenue as of September 30, 2023.

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 Condensed Consolidated Balance Sheet and will be periodically assessed for impairment. During the year ending December 31, 2022, $4.0 million was reclassified as prepaid expenses and other current assets. During the three and nine months ended September 30, 2023, $1.4 million and $4.0 million in equipment and services was received, respectively, which brought the remaining advanced payments to $6.0 million, with $1.1 million recorded in prepaid expenses and other current assets and $4.9 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 Foundation Medicine Agreement has an initial term of five years, expiring in August 2024, with automatic renewals thereafter for successive one-year terms, unless the Foundation Medicine Agreement is earlier terminated in accordance with its terms. Natera and Foundation Medicine will share the revenues generated from both biopharmaceutical and clinical customers in accordance with the terms of the Foundation Medicine Agreement.

18

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. Revenues associated with each of the performance obligations are recognized over time using the input method, based on costs incurred to perform the development services, since the level of costs incurred over time best reflect the transfer of development services. Revenue associated with the assay testing services will be recognized upon delivery of these services. Funds received in advance are recorded as deferred revenue and will be recognized as the related services are delivered.

The initial transaction price was primarily comprised of license and milestone fees. 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. Certain milestone fees were constrained and not included in the transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The allocation of the transaction price was performed based on standalone selling prices, which are based on estimated amounts that the Company would charge for a performance obligation if it were sold separately.

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 and $2.9 million was recognized in the nine months ended September 30, 2023 and 2022, respectively. 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 nine months ended September 30, 2023 and 2022, the Company recognized $0.3 million and $0.1 million, respectively, related to oncology assay interpretation services. The Company currently has $3.9 million in deferred revenue as of September 30, 2023.

Disaggregation of Revenues

The Company measures its performance results primarily based on revenues recognized from the three categories described below. The following table shows disaggregation of revenues by payer types:

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:

As of September 30, 2023, the estimated fair value of the total principal outstanding and accrued interest of the Credit Line, which are not presented at fair value on the Condensed Consolidated Balance Sheets for both September 30, 2023 and December 31, 2022, 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 1.21%.

As of September 30, 2023, the estimated fair value of the Convertible Notes, which are not presented at fair value on the Condensed Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, was $391.4 million and $358.4 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.

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:

	September 30, 2023						December 31, 2022
	Amortized Cost		Gross Unrealized Loss		Estimated Fair Value		Amortized Cost		Gross Unrealized Gain		Gross Unrealized Loss		Estimated Fair Value

Cash, cash equivalents and restricted cash (2)						668,710								466,091
Short-term investments						267,847								432,301
Total					$	936,557							$	898,392

(1) Per the Company’s investment policy, all debt securities are classified as short-term investments irrespective of holding period.  

(2) Cash equivalents includes money market deposits and liquid demand deposits.

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 nine months ended September 30, 2023, the Company did not 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 September 30, 2023, the Company had 38 investments in an unrealized loss position in its portfolio. An allowance for credit losses was not necessary as the decrease in the fair market value for a majority of these available-for-sale securities was as a result of a significant average yield rate increase for similar securities as of September 30, 2023. The Company has assessed the unrealized loss position for available-for-sale debt securities for which an allowance for credit losses has not been recorded and concluded any such losses are temporary and not indicative of an impairment as these investments will be held until maturity or price recovery.

The following table presents debt securities available-for-sale that were in an unrealized loss position as of September 30, 2023, aggregated by major security type in a continuous loss position. There were no debt securities available-for-sale in an unrealized loss position for less than 12 months as of September 30, 2023.

23

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

During the nine months ended September 30, 2023, 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 $16.1 million recorded in the nine months ended September 30, 2023. Depreciation expense of $12.2 million was recorded in the nine months ended September 30, 2022. The Company did not incur any impairment charges during the nine months ended September 30, 2023.

7. Leases

Operating Leases

In September 2015, the Company’s subsidiary 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 includes two additional office spaces (the “First Expansion Premises” and the

24

“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 of two 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. The term of this lease is approximately 84 months and expires in October 2023. This lease contains an option to renew the lease term for five years, but the fair market rent amount upon renewal is not available from the landlord. 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 will be $9.3 million commencing 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 for five 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 by three 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 will be used for laboratory and research use and is expected to commence 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 starts 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 approximating one to five 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 nine months ended September 30, 2023, the Company had $0.1 million in noncash operating activities related to additional right-of-use assets accounted for exercising the option to extend a lease under ASC 842. For the nine months ended September 30, 2022, the Company had noncash operating activities of $22.1 million primarily related to additional right-of-use assets related to the Austin First and Second Expansion Premises commenced in February 2022 and September 2022, respectively, which was accounted for as a new lease under ASC 842.

25

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:

	September 30,		December 31,
	2023		2022
		(in thousands)
Operating lease liabilities, current portion included in other accrued liabilities	$	11,038	$	7,639
Operating lease liabilities, long-term portion		68,287		76,577
Total operating lease liabilities	$	79,325	$	84,216

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 September 30, 2023, the weighted-average remaining lease term was 6.94 years and the weighted-average discount rate was 6.67%.

The Company continues to recognize lease expense on a straight-line basis. The lease expense includes the amortization of the right-of-assets with the associated interest component estimated by applying the effective interest method. For the three months ended September 30, 2023 and 2022, total lease expense of $3.6 million and $3.5 million was recognized in the condensed statements of operations and comprehensive loss, respectively. For the nine months ended September 30, 2023 and 2022, total lease expense of $11.0 million and $10.0 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 $3.2 million and $1.7 million for the three months ended September 30, 2023 and 2022, respectively. Cash paid for amounts in the measurement of operating lease liabilities totaled $8.4 million and $7.2 million for the nine months ended September 30, 2023 and 2022, respectively.

The present value of the future annual minimum lease payments under all non-cancellable operating leases as of September 30, 2023 are as follows:

	Operating Leases
	(in thousands)
As of September 30, 2023
2023 (remaining 3 months)	$	3,983

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.

An independent committee of the Company’s board of directors initiated and has completed an internal investigation into the allegations made in a March 2022 short seller report, with the assistance of the law firm of WilmerHale LLP. WilmerHale had access to company executives, personnel, records, communications, and documents. Based on the investigation, the independent committee, on behalf of the board, has concluded that the allegations of wrongdoing against the Company in the report were unfounded.

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 the financial statements.  

Intellectual Property Litigation Matters.

The Company has been involved in two 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 (“Stanford”) 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 all three 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 alleges, in suits filed in January 2020 and May 2022, infringement by CareDx of three of the Company’s patents, seeking unspecified damages and injunctive relief. The case is currently pending and is scheduled for trial in January 2024.

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 Corp. (“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. A jury trial was held in May 2023, after which the jury returned a verdict in favor of the Company, finding all three asserted patents valid and infringed by ArcherDX and

27

Invitae and awarding damages totaling $19.35 million to the Company. A bench trial was held in June 2023 on defendants’ remaining equitable defense against two of the Natera patents; the court issued an order denying the defendants’ equitable defense in September 2023. Also in June 2023, the Company moved for a permanent injunction against the PCM test, which motion remains pending before the court. The court has entered an interim judgment in favor of the Company pursuant to the May 2023 jury verdict and the September 2023 court order. ArcherDX and Invitae have filed post-trial motions in response to the interim judgment. The Company intends to oppose the motions.

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 of two Ravgen patents. The complaint seeks monetary damages and injunctive relief. Various parties, including Natera, 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. The lawsuit is currently scheduled for trial in January 2024.

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 infringe one 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 January 2021, the Company filed suit against Inivata, Inc. and Inivata Ltd. (collectively “Inivata”) in the United States District Court for the District of Delaware. The complaint, amended by the Company in May 2021, alleges that various Inivata oncology products infringe two of the Company’s patents and seeks unspecified monetary damages and injunctive relief. Inivata filed a motion to dismiss the Company’s amended complaint, which the Court denied. In December 2022, the Company filed a second suit against Inivata in the same district court, alleging that certain of Inivata’s oncology products additionally infringe a third patent of the Company’s, and seeking unspecified monetary damages and injunctive relief. The two suits have been consolidated. Inivata has filed a motion to dismiss the Company’s second complaint, which motion is currently pending before the Court.

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. Trial is currently scheduled for March 2024.

In July 2023, the Company filed suit against NeoGenomics Laboratories, Inc. (“NeoGenomics”) in the United States District Court for the Middle District of North Carolina, alleging infringement of certain Natera patents by NeoGenomics’ commercialization of the RaDaR test. The complaint seeks monetary damages and injunctive relief. The Company filed a motion for preliminary injunction, which is pending before the Court.

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 Natera 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. On July 17, 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 Natera, ruling that CareDx is not entitled to any damages. Both parties have filed notices of appeal.

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

28

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 March 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, to which the Company expects to file a response.

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 October 2023, a shareholder derivative complaint was filed in the United States District Court for the Western District of Texas against the Company as nominal defendant and certain of the Company’s management, alleging, 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.

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.  

29

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.

9. Stock-Based Compensation

2015 Equity Incentive Plan

General.  The Company’s board of directors adopted its 2015 Equity Incentive Plan (the “2015 Plan”) in June 2015. The 2015 Plan replaced the Company’s prior stock plans.

Share Reserve.  The initial number of shares of the Company’s common stock available for issuance under the 2015 Plan was 3,451,495 shares. The number of shares reserved for issuance under the 2015 Plan will be increased automatically on the first business day of each fiscal year, commencing in 2016, by a number equal to the least of:

● 3,500,000 shares;

● 4% of the shares of common stock issued and outstanding on the last business day of the prior fiscal year; or

● a number of shares determined by the Company’s board of directors.

Stock options vest as determined by the compensation committee. In general, they will vest over a four-year period following the date of grant. Stock options expire at the time determined by the compensation committee but in no event more than ten years after they are granted. These awards generally expire earlier if the participant's service terminates earlier.

Restricted Shares and Stock Units.  Restricted shares and stock units (“RSUs”) may be awarded under the 2015 Plan in return for any lawful consideration, and participants who receive restricted shares or stock units generally are not required to pay cash for their awards. In general, these awards will be subject to vesting. Vesting may be based on length of service, the attainment of performance-based milestones or a combination of both, as determined by the compensation committee.

Employee Stock Purchase Plan

During the period ended September 30, 2023, there have not been any changes to the Company’s 2015 Natera, Inc. Employee Stock Purchase Plan (the “ESPP”) as disclosed in Form 10-K for the fiscal year ended December 31, 2022.  

30

The Company has made 3,964,612 shares available for issuance under the Plan as of September 30, 2023, a number that is automatically increased on the first business day of each fiscal year of the Company during the term of the ESPP by the least of (i) 1% of the total number of shares of common stock actually issued and outstanding on the last business day of the prior fiscal year, (ii) 880,000 shares of common stock (subject to the ESPP), or (iii) a number of shares of common stock determined by the Company’s board of directors.

The first offering period of 2023 started on November 1, 2022 and ended on April 30, 2023. As of September 30, 2023, 218,649 shares have been purchased in the first offering period. The second offering period of 2023 began on May 1, 2023 and ended on October 31, 2023.

Performance-based Awards

The Company grants certain senior-level executives performance stock options and units which vest based on either market and time-based service conditions or performance and time-based service conditions, which are referred to herein as performance-based awards. The Company assessed the performance-based awards with the appropriate valuation method and has recognized the applicable stock-based compensation expense.

The Company has recognized $23.0 million and $12.4 million in stock-based compensation for performance-based awards for the three months ended September 30, 2023 and 2022, respectively. The Company has recognized $40.5 million and $40.0 million in stock-based compensation for performance-based awards for the nine months ended September 30, 2023 and 2022, respectively. There were no performance-based awards with market conditions and a fair value estimated using a Monte Carlo simulation model granted in the nine months ended September 30, 2023 and 2022.

Restricted Stock Units

The following table summarizes unvested RSU for the nine months ended September 30, 2023:

		Weighted-
		Average
		Grant Date
(in thousands, except for grant date fair value)	Shares	Fair Value
Balance at December 31, 2022	6,836	$	57.12

Vested	(2,364)	$	57.01
Cancelled/forfeited	(760)	$	50.01
Balance at September 30, 2023	9,440	$	50.28

Stock-Based Compensation Expense

Stock based compensation is related to stock options and RSUs granted to the Company’s employees and is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period of the respective awards on a straight-line basis. If awards have both a service condition and performance or market condition, then an accelerated expense method is used. No compensation cost is recognized when the requisite service has not been met and the awards are therefore forfeited.

Employee stock-based compensation expense is calculated based on awards ultimately expected to vest and has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates. Non-employee stock-based compensation expense is not adjusted for estimated forfeitures up until the occurrence of the actual forfeiture of the associated awards.

The following tables present the effect of employee and non-employee stock-based compensation expense on selected statements of operations line items for the three and nine months ended September 30, 2023 and 2022.

	Three months ended September 30,

32

As of September 30, 2023, approximately $368.4 million of unrecognized compensation expense, adjusted for estimated forfeitures, related to unvested option awards and RSUs will be recognized over a weighted-average period of approximately 2.5 years.

Valuation of Stock Option Grants to Employees and Non-employees

The Company utilizes the Black-Scholes option pricing model when estimating the fair value of stock options. For the three and nine months ended September 30, 2023, the following valuation assumptions were applied on both the employee and non-employee options.

	Three months ended September 30,						Nine months ended September 30,
	2023			2022			2023					2022
Expected term (years)		6.03			6.05		5.20		—	6.03		5.12		—	10.00
Expected volatility		68.23	%		61.63	%	68.23	%	—	70.07	%	55.91	%	—	62.30	%
Expected dividend rate		—	%		—	%				—	%				—	%
Risk-free interest rate		4.18	%		3.15	%	3.41	%	—	4.18	%	1.62	%	—	3.15	%

As of September 30, 2023, total stock options outstanding include stock options for 23,005 shares of common stock that were granted to non-employees, of which none are vested. Stock-based compensation expense related to stock options granted to non-employees is recognized as the stock option is earned and the services are rendered. The Company believes that the estimated fair value of the stock options is more readily measurable than the fair value of the services rendered.

10. Debt

Credit Line Agreement

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 September 30, 2023 was 6.53%. 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. 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. As of September 30, 2023, 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 October 2023, the interest rate for the Credit Line was subsequently changed to the 30-day SOFR average, plus 0.5%.

For the three months ended September 30, 2023 and 2022, the Company recorded interest expense on the Credit Line of $1.3 million and $0.4 million, respectively. For the nine months ended September 30, 2023 and 2022, the Company recorded interest expense on the Credit Line of $3.7 million and $0.8 million, respectively. Interest payments on the Credit Line were made within the same periods. As of September 30, 2023 and December 31, 2022, the total principal amount outstanding with accrued interest was $80.4 million.

Convertible Notes

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

33

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. The Company used approximately $79.2 million of the net proceeds from the Convertible Notes offering to repay its obligations under the 2017 Term Loan with OrbiMed.

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:  

● During any fiscal quarter commencing after March 31, 2020 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day.

● During the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Notes for each trading day of that five-day consecutive trading period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day.

● If the Company calls any or all of the Convertible Notes for redemption at any time prior to the close of business on the second business day prior to the redemption date.

● Upon the occurrence of certain distributions.

● Upon the occurrence of specified corporate transactions.

The first two circumstances have been met as of September 30, 2023. However, there were no conversions for the period ending September 30, 2023.

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, 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

34

Convertible Notes or approximately its seven-year term. The outstanding Convertible Notes balances as of September 30, 2023 and December 31, 2022 are summarized in the following table:

	September 30, 2023		December 31, 2022
	(in thousands)
Long-Term Debt

11. Income Taxes

During the three months ended September 30, 2023 and 2022, the Company recorded total income tax expense of approximately $202,000 and $185,000, respectively. During the nine months ended September 30, 2023 and 2022, the Company recorded total income tax expense of approximately $80,000 and $557,000, respectively. The income tax expense is primarily attributable to state income tax and foreign income tax expenses resulting from testing to clinics and licenses of cloud-based software and intellectual property that are based in a foreign country. 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 September 30, 2023. 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 September 30, 2023 and December 31, 2022, there were no accrued interest and penalties related to uncertain tax positions.

35

12. Net Loss per Share

The Convertible Notes are convertible by the holders as of September 30, 2023. 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 shares issued to settle the Convertible Notes would exceed the Convertible Note principle by $105.7 million based on the closing price of the Company’s common stock as of September 30, 2023. 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 September 30, 2023 and 2022:

	September 30,
	2023	2022

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our unaudited condensed consolidated financial statements and related notes included in Part I, Item 1 of this report. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission on March 1, 2023.

Overview

We are a diagnostics company with proprietary molecular and bioinformatics technology that we are applying to change the management of disease worldwide. We began in the women’s health space, in which we develop and commercialize 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. Our technology is now also being used in the oncology market, in which we are commercializing, among others, a personalized blood-based DNA test to detect molecular residual disease and monitor disease recurrence, as well as in the organ health market, with tests to assess organ transplant rejection. We seek to enable even wider adoption of our technology through Constellation, our global cloud-based distribution model. In addition to our direct sales force in the United States, we have a global network of over 100 laboratory and distribution partners, including many of the largest international laboratories.

We currently provide a comprehensive suite of products in women’s health, as well as our oncology and organ health products, and our Constellation cloud-based platform. We generate a majority of our revenues from the sale of Panorama, our non-invasive prenatal test (“NIPT”), as well as Horizon, our Carrier Screening (“HCS”) test. In addition to Panorama and Horizon, our product offerings in women’s health include Spectrum Preimplantation Genetics, our Anora miscarriage test, and Vistara single-gene NIPT, as well as our Empower hereditary cancer screening test, which we also plan to offer to oncologists through our oncology sales channel. We also offer our Signatera molecular residual disease test for oncology applications, which we commercialize as a test run in our CLIA (as defined below) laboratory and offer on a research use only basis to research laboratories and pharmaceutical companies; and our Prospera organ transplant assessment tests.

We process tests in our laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) in Austin, Texas and San Carlos, California. A portion of our testing is performed by third-party laboratories. Our customers include independent laboratories, national and regional reference laboratories, medical centers and physician practices for our screening tests, and research laboratories and pharmaceutical companies. We market and sell our tests through our direct sales force and, for our women’s health tests, through our laboratory distribution partners. We bill clinics, laboratory distribution partners, patients, pharmaceutical companies and insurance payers for the tests we perform. In cases where we bill laboratory distribution partners, our partners in turn bill clinics, patients and insurers. The majority of our revenue comes from insurers with whom we have in-network contracts. Such insurers reimburse us for our tests pursuant to our in-network contracts with them, based on positive coverage determinations, which means that the insurer has determined that the test in general is medically necessary for this category of patient.

In addition to offering tests to be performed at our laboratories, either directly or through our laboratory distribution partners, we also establish licensing arrangements with laboratories under Constellation, our cloud-based distribution model, whereby our laboratory licensees run the molecular workflows themselves and then access our bioinformatics algorithms through our cloud-based software. This cloud-based distribution model results in lower revenues and gross profit per test than cases in which we process a test ourselves; however, because we do not incur the costs of processing the tests, our costs per test under this model are also lower. We began entering into these licensing arrangements starting in the fourth quarter of 2015.

The principal focus of our commercial operations is to offer our tests through both our direct sales force and laboratory distribution partners, and our Constellation licensees under our cloud-based distribution model. The number of tests that we accession is a key indicator that we use to assess our business. A test is accessioned when we receive the test

37

at our laboratory, the relevant information about the test is entered into our computer system, and the test sample is routed into the appropriate workflow. This number is a subset of the number of tests that we process, which includes tests distributed through our Constellation licensees. The number of tests that we process is a key metric as it tracks overall volume growth, particularly as our laboratory partners may transition from sending samples to our laboratory to our cloud-based distribution model, as a result of which our tests accessioned would decrease but our tests processed would remain unchanged.

During the nine months ended September 30, 2023, we processed approximately 1,869,400 tests, comprised of approximately 1,816,500 tests accessioned in our laboratory, compared to approximately 1,506,700 tests processed, comprised of approximately 1,460,100 tests accessioned in our laboratory, during the nine months ended September 30, 2022. This increase in volume primarily represents continued commercial growth of Signatera, Panorama and HCS, both as tests performed in our laboratory as well as through our Constellation software platform.

The percent of our revenues attributable to our U.S. direct sales force for the nine months ended September 30, 2023 was 91%, a slight increase compared to 89% for the nine months ended September 30, 2022. The percent of our revenues attributable to U.S. laboratory distribution partners for the nine months ended September 30, 2023 was 6%, a slight decrease compared to 7% from the same period in the prior year. Our ability to increase our revenues and gross profit will depend on our ability to further penetrate the U.S. market with our direct sales force. The percent of our revenues attributable to international laboratory distribution partners and other international sales for the nine months ended September 30, 2023 was 3%, a slight decrease from 4% in the nine months ended September 30, 2022.

For the nine months ended September 30, 2023, total revenues were $771.5 million compared to $603.0 million in the nine months ended September 30, 2022. Product revenues accounted for $761.3 million, 99% of total revenues for the nine months ended September 30, 2023 compared to $584.4 million representing 97% of total revenues for the nine months ended September 30, 2022. For the nine months ended September 30, 2023 and 2022, no customers exceeded 10% of the total revenues on an individual basis. Revenues from customers outside the United States were $25.0 million, representing approximately 3% of total revenues for the nine months ended September 30, 2023. For the nine months ended September 30, 2022, revenues from customers outside the United States were $26.8 million, representing approximately 4% total revenues. Most of our revenues have been denominated in U.S. dollars, though we generate some revenue in foreign currency, primarily denominated in Euros and Singapore Dollars.

Our net loss for the nine months ended September 30, 2023 and 2022 was $356.8 million and $405.2 million, respectively. This included non-cash stock compensation expense of $142.9 million and $116.4 million for the nine months ended September 30, 2023 and 2022, respectively. As of September 30, 2023, we had an accumulated deficit of $2.3 billion.

Components of the Results of Operations

Revenues

We generate revenues from the sale of our tests, primarily from the sale of our Signatera, Panorama and HCS tests. Our two primary distribution channels are our direct sales force and our laboratory partners. In cases where we promote our tests through our direct sales force, we generally bill directly to a patient, clinic or insurance carrier, or a combination of the insurance carrier and patient, for the fees.

Sales of our clinical tests are recorded as product revenues. Revenues recognized from tests processed through our Constellation model, from the Qiagen LC (“Qiagen”), BGI Genomics Co. Ltd., and Foundation Medicine, Inc. agreements (collectively the “Strategic Partnership Agreements”) are reported in licensing and other revenues.

In cases where we sell our tests through our laboratory partners, the majority of our laboratory partners bill the patient, clinic or insurance carrier for the performance of our tests, and we are entitled to either a fixed price per test or a percentage of their collections.

38

Our ability to increase our revenues will depend on our ability to further penetrate the domestic and international markets and, in particular, generate sales through our direct sales force, develop and commercialize additional tests, obtain reimbursement from additional third-party payers and increase our reimbursement rate for tests performed. In particular, our financial performance depends on reimbursement for Panorama in the average risk population and for microdeletions. There has been a significant increase in the number of commercial third-party payers that cover the use of Panorama in the average risk population, representing approximately 95% of commercial covered lives in the United States, as well as an increasing number of state Medicaid payers expanding coverage to average risk pregnancies. Many third-party payers do not currently reimburse for microdeletions screening in part because there is currently limited published data on the performance of microdeletions screening tests. A new current procedure terminology (“CPT”) code for microdeletions went into effect beginning January 1, 2017. We have experienced low average reimbursement rates thus far for microdeletions testing under this new code, and we expect that this new code will cause, at least in the near term, our microdeletions reimbursement to remain low, due to third-party payers declining to reimburse and through reduced reimbursement under the new code. This has had, and we expect it will continue to have, an adverse impact on our revenues. In addition, a new CPT code for expanded carrier screening went into effect beginning January 1, 2019, and has had, and may continue to have, an adverse effect on our reimbursement rates for our broader Horizon carrier screening panel for which we previously primarily received reimbursement on a per-condition basis, as those tests may be reimbursed as a combined single panel instead of as multiple individual tests. Because our revenues from Horizon continue to represent an increasing proportion of our overall revenues, a decline in our reimbursement rates for, and therefore our average selling price of, Horizon, could result in a decline in our overall revenue.

Our financial performance has also been impacted by the increase in in-network coverage of our tests by third-party payers, which we believe is crucial to our growth and long-term success. However, because the negotiated fees under our contracts with third-party payers are typically lower than the list price of our tests, as we enter into additional in-network contracts with insurance providers, our average reimbursement per test may decrease as compared to out-of-network contracts. While we expect the reduction in average reimbursement per test from in-network pricing to reduce our revenues and gross margins in the near term, in-network pricing is more predictable than out-of-network pricing, and we intend to continue to mitigate the impact by driving more business from our most profitable accounts.

Cost of Product Revenues

The components of our cost of product revenues are material and service costs, impairment charges associated with testing equipment, personnel costs, including stock-based compensation expense, equipment and infrastructure expenses associated with testing samples, electronic medical records, order and delivery systems, shipping charges to transport samples, costs incurred from third party test processing fees, and allocated overhead such as rent, information technology costs, equipment depreciation and utilities. Costs associated with Whole Exome Sequencing (“WES”) are also included, as well as labor costs, relating to our Signatera CLIA and Signatera research use only offerings. Costs associated with performing tests are recorded when the test is accessioned and processed. We expect cost of product revenues in absolute dollars to increase as the number of tests we perform increases.

As we continue to achieve scale, we have increased our focus on more efficient use of labor, automation, and DNA sequencing. For example, we updated the molecular and bioinformatics process for Panorama to further reduce the sequencing reagents, test steps and associated labor costs required to obtain a test result, while increasing the accuracy of the test to allow it to run with lower fetal fraction input. These improvements also reduced the frequency of the need to require blood redraws from the patient.

Cost of Licensing and Other Revenues

The components of our cost of licensing and other revenues are material costs associated with test kits sold to Constellation clients, development and support services relating to our Strategic Partnership Agreements, and costs associated with specimens and WES.

We currently have 11 revenue generating licensing and service agreements with laboratories under our Constellation distribution model. We consider our cost of licensing and other revenues for the Constellation software

39

platform to be relatively low, and therefore we expect its associated gross margin is higher. We expect our cost of licensing will increase in relation to volume growth.

Critical Accounting Policies

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated, and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We consider our critical accounting policies and estimates to be revenue recognition, leases, fair value measurements, and stock-based compensation.

There have been no material changes to our other critical accounting policies and estimates as compared to the disclosures in our Annual Report on Form 10-K for the year ended December 31, 2022.

Recent Accounting Pronouncements

We believe that the impact of accounting standards updates recently issued that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

Revenues

Total revenues are comprised of product revenues, which are primarily driven by sales of our Panorama and HCS tests, oncology testing, and licensing and other revenues, which primarily includes development licensing revenue and

40

licensing of our Constellation software. Total revenues increased by $57.7 million, or 27.4%, when compared to the three months ended September 30, 2022.

We derive our revenues from tests based on units reported to customers—tests delivered with a result. All reported units are either accessioned in our laboratory or processed outside of our laboratory. As noted in the section titled “Overview” above, the number of tests that we process is a key metric as it tracks our overall volume growth. During the three months ended September 30, 2023, total reported units were approximately 590,000, comprised of approximately 575,000 tests reported in our laboratory. Comparatively, during the nine months ended September 30, 2022, total reported units were approximately 482,900, comprising of approximately 469,200 tests reported in our laboratory. During the three months ended September 30, 2023 and 2022, total oncology units processed were approximately 88,700 and 53,200, respectively.

Product Revenues

During the three months ended September 30, 2023, product revenues increased by $65.4 million, or 32.7% compared to the three months ended September 30, 2022, primarily as a result of the continued revenue growth from increased test volumes as well as average selling price improvements.

Licensing and Other Revenues

Licensing and other revenues decreased by $7.7 million, or 71.4%, during the three months ended September 30, 2023 when compared to the three months ended September 30, 2022. The decrease was primarily due to a decrease in revenue from our collaborative agreements.

Cost of Product Revenues

During the three months ended September 30, 2023, cost of product revenues increased compared to the three months ended September 30, 2022 by approximately $31.5 million, or 27.3%, due to a $9.1 million increase in third-party billing fees, higher costs related to inventory consumption of $11.2 million driven by an increase in accessioned tests, a $2.8 million increase in equipment and related depreciation expense, and a $8.4 million increase in labor, overhead, shipping and other related costs driven by headcount growth and product support.

Cost of Licensing and Other Revenues

Cost of licensing and other revenues for the three months ended September 30, 2023, when compared to the three months ended September 30, 2022, decreased by $0.7 million, or 67.6%, primarily due to a net decrease in costs to support our collaborative agreements.

Research and Development

Research and development expenses during the three months ended September 30, 2023, increased by $11.7 million, or 17.9%, when compared to the three months ended September 30, 2022. The increase was attributable to a $6.6 million increase in salary and related compensation expenditures, which includes a $5.5 million increase in stock-based compensation expense, and a $6.5 million increase primarily due to a one-time benefit to in-process research and development expense in the third quarter of 2022. This was offset by a $1.4 million net decrease in lab and clinical trial related expenses, consulting, travel, facilities, and other expenses.

Selling, General and Administrative

Selling, general and administrative expenses increased by $7.1 million, or 4.8%, during the three months ended September 30, 2023 compared to the three months ended September 30, 2022. The increase was attributable to a net increase of $6.0 million in salary and related compensation expenditures primarily related to an increase in stock-based compensation expense and a $4.5 million increase in third party billing expenses. This was offset by a $3.4 million net decrease in marketing, travel, facilities, office and other costs.

41

Interest Expense

Interest expense increased by $0.9 million in the three months ended September 30, 2023 compared to the same period in the prior year. The interest expense increased primarily as a result of the increase in interest rate compared to the same period in prior year and the $30.0 million drawdown from November 2022 of the Credit Line.

Interest and Other Income

Interest and other income for the three months ended September 30, 2023 increased $5.3 million compared to the same period in the prior year, primarily due to greater cash and investment balances driving higher interest income.

Interest and other income for the nine months ended September 30, 2023 increased $13.3 million compared to the same period in the prior year, primarily due to greater cash and investment balances driving higher interest income.

43

Liquidity and Capital Resources

We have incurred net losses each year since our inception. For the nine months ended September 30, 2023, we had a net loss of $356.8 million, and we expect to continue to incur losses in future periods as we continue to devote a substantial portion of our resources to our research and development and commercialization efforts for our existing and new products. As of September 30, 2023, we had an accumulated deficit of $2.3 billion. We had $668.7 million in cash and cash equivalents and restricted cash, $267.8 million in marketable securities, 80.4 million of outstanding balance of the Credit Line including accrued interest, and $287.5 million outstanding principal balance on the Convertible Notes. As of September 30, 2023, we had $20.0 million remaining and available on the Credit Line.

While we have introduced multiple products that are generating revenues, these revenues have not been sufficient to fund all operations. Accordingly, we have funded the portion of operating costs that exceeds revenues through a combination of equity issuances and debt and other financings. We expect to develop and commercialize future products and continue to invest in the growth of our business and, consequently, we will need to generate additional revenues to achieve future profitability and may need to raise additional equity or incur additional debt. If we raise additional funds by issuing equity securities, our stockholders would experience dilution. Additional debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any additional debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders and requires significant debt service payments, which diverts resources from other activities. Additional financing may not be available at all, or in amounts or on terms acceptable to us. If we are unable to obtain additional financing, we may be required to delay the development and commercialization of our products and significantly scale back our business and operations.

In September 2023, we completed an underwritten equity offering and sold 4,550,000 shares of our common stock at a price of $55 per share to the public. Before estimated offering expenses of $0.4 million, we received proceeds of approximately $235.8 million net of the underwriting discount. In November 2022, we completed an underwritten equity offering and sold 13,144,500 shares of our common stock at a price of $35 per share to the public. Before estimated offering expenses of $0.5 million, we received proceeds of approximately $433.2 million net of the underwriting discount. As cash flows from our operations are currently negative, our contractual obligations and other commitments are satisfied by the equity offering described above, our convertible note financing conducted in April 2020 described below, the Credit Line described below, and our product, licensing, and other sales. For our commitments, refer to the “Contractual Obligations and Other Commitments” section below.

Refer to additional disclosures associated with risks and our ability to generate and obtain adequate amounts of cash to meet capital requirements for both short-term and long-term obligations.

Based on our current business plan, we believe that our existing cash and marketable securities will be sufficient to meet our anticipated cash requirements for at least 12 months after November 8, 2023.

Credit Line Agreement

In September 2015, we entered into a Credit Line with UBS (“the Credit Line”) providing for a $50.0 million revolving line of credit which could be drawn in increments at any time. The Credit Line was amended in July 2017 and bears interest at 30-day LIBOR plus 1.10%, and it is secured by a first priority lien and security interest in our money market and marketable securities held in our managed investment account with UBS. The interest rate was subsequently changed to the 30-day Secured Overnight Financing Rate (“SOFR”) average, plus 1.21%. The SOFR rate is variable. UBS has the right to demand full or partial payment of the Credit Line obligations and terminate it, in its discretion and without cause, at any time. The Credit Line was subsequently increased from $50.0 million to $150.0 million. In June 2023, the Credit Line decreased to $100.0 million. As of September 30, 2023, the total principal amount outstanding with accrued interest was $80.4 million. In October 2023, the interest rate for the Credit Line was subsequently changed to the 30-day SOFR average, plus 0.5%.

44

Convertible Notes

In April 2020, we issued $287.5 million aggregate principal amount of Convertible Notes 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 in arrears in May and November of each year, beginning in November 2020. 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 our common stock or a combination of cash and shares of our common stock, at our election.

We received net proceeds from the Convertible Notes of $278.3 million, after deducting the initial purchasers’ discounts and debt issuance costs. We used approximately $79.2 million of the net proceeds from the Convertible Notes offering to repay our obligations under our 2017 Term Loan with OrbiMed.

We have entered into arrangements that contractually obligate us to make payments that will affect our liquidity and cash flows in future periods. Such arrangements include those related to our lease commitments, Credit Line (as defined below), Convertible Notes, commercial supply agreements and other agreements.

Credit Line

The short-term debt obligations consist of the $80.4 million principal amount drawn from the UBS Credit Line (the “Credit Line’) and applicable interest. The Credit Line was amended in July 2017 and bears interest at 30-day LIBOR plus 1.10%, and it is secured by a first priority lien and security interest in our money market and marketable securities held in our managed investment account with UBS. The interest rate was subsequently changed to the 30-day SOFR average, plus 1.21%. The SOFR rate is variable. UBS has the right to demand full or partial payment of the Credit Line obligations and terminate it, in its discretion and without cause, at any time. In October 2023, the interest rate was subsequently changed to the 30-day SOFR average, plus 0.5%. Please refer to Note 10, Debt, for further details.

Convertible Notes

The long-term debt obligations consist of the $287.5 million principal amount from a private placement offering to qualified institutional buyers and applicable interest. 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 in arrears in May and November of each year, beginning in November 2020. 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 our common stock or a combination of cash and shares of our common stock, at our election. Please refer to Note 10, Debt, for further details.

46

Inventory purchase and other contractual obligations

We enter into contracts in the normal course of business with various third parties for clinical trials, preclinical research studies, testing, manufacturing, and other services for operational purposes. Payments due upon cancellation generally consist only of payments for services provided or expenses incurred, including non-cancellable obligations of our service providers, up to the date of cancellation. These payments have not been included separately within these contractual and other obligations disclosures. Please refer to Note 8, Commitments and Contingencies in the Notes to Unaudited Interim Condensed Consolidated Financial Statements for further details.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements during the periods presented.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rates. Our Credit Line has an interest rate of 30-day LIBOR plus 1.10%. The interest rate was subsequently changed to the 30-day Secured Overnight Financing Rate (“SOFR”) average, plus 1.21%. The SOFR rate is variable. An incremental change in the borrowing rate of 100 basis points would increase our annual interest expense by $0.8 million based on our $80.4 million gross debt outstanding on our Credit Line, including principal and accrued interest as of September 30, 2023. The interest rate for our Convertible Notes is fixed at 2.25% and not exposed market risk related to interest rates. Our investment portfolio is exposed to market risk from changes in interest rates. This risk is mitigated as we have maintained a relatively short average maturity for our investment portfolio. An incremental change in the investment yield of 100 basis points would increase our annual interest income by approximately $2.7 million annually in relation to amounts we would expect to earn, based on our short-term investments as of September 30, 2023. In October 2023, the interest rate for the Credit Line was subsequently changed to the 30-day SOFR average, plus 0.5%.

Foreign Currency Exchange Rate Fluctuations

Our operations are currently conducted primarily in the United States. As we expand internationally, our results of operations and cash flows may become subject to fluctuations due to changes in foreign currency exchange rates. In periods when the U.S. dollar declines in value as compared to the foreign currencies in which we incur expenses, our foreign currency-based expenses will increase when translated into U.S. dollars. In addition, future fluctuations in the value of the U.S. dollar may affect the price at which we sell our tests outside the United States. To date, our foreign currency risk has been minimal, and we have not historically hedged our foreign currency risk; however, we may consider doing so in the future.

Inflation Risk

As of the date of filing of this Quarterly Report, we do not believe that inflation has had a material effect on our business, financial condition, or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through increases in revenue as increases in core inflation rates may also negatively affect demand for our product offerings. Our inability or failure to do so could harm our business, financial condition, and results of operations.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2023. The term “disclosure controls and procedures,” as defined in Rule 13a-15(e) under the Exchange Act, means controls and other procedures of a company

47

that are 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 recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’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 our management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Based on the evaluation of our disclosure controls and procedures as of September 30, 2023, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II – OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

From time to time, we are involved in legal proceedings. The results of such legal proceedings and claims cannot be predicted with certainty, and regardless of the outcome, legal proceedings could have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors.

For information regarding certain current legal proceedings, see “Note 8—Commitments and Contingencies—Legal Proceedings” in the Notes to Unaudited Interim Condensed Consolidated Financial Statements, which is incorporated herein by reference.

48

ITEM 1A.RISK FACTORS

Investing in our common stock involves a high degree of risk. In addition to the information set forth in this Quarterly Report on Form 10-Q, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, you should consider carefully the factors discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission on March 1, 2023. The occurrence of any of the risks and uncertainties described in such Annual Report could materially and adversely affect our business, financial condition, results of operations and prospects. In that event, the price of our common stock could decline and you could lose part or all of your investment. Furthermore, such risks are not the only ones we face; additional risks and uncertainties not currently known or that we currently deem to be immaterial may also materially adversely affect our business, financial condition or results of operations.

Such trading arrangement was not intended to satisfy the affirmative defense conditions of Securities Exchange Act Rule 10b5-1(c), but complied with the then-applicable requirements of Rule 10b5-1(c) when adopted in September 2021. Such trading arrangement provided for the sale of up to 50,910 shares between April 1, 2022 and May 1, 2022.

Description of Business

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’s technology has been proven clinically and commercially in the women’s health space, in which it 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.  The Company is now translating its success in women’s health and applying its core technology to the oncology market, in which it is commercializing a personalized blood-based DNA test to detect molecular residual disease and monitor disease recurrence, as well as to the organ health market, initially with a test to assess kidney transplants for rejection. The Company operates laboratories in Austin, Texas and San Carlos, California certified under the Clinical Laboratory Improvement Amendments ("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 operates one 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 ("NIPT") 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 ("HCS") to determine carrier status for a large number of severe genetic diseases that could be passed on to the carrier’s children; Signatera molecular residual disease (“MRD”) test, which detects circulating tumor DNA in patients previously diagnosed with cancer to assess molecular residual disease and monitor for recurrence; and Prospera, to assess organ transplant rejection. All testing is available principally in the United States. The Company does not conduct animal testing. 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.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

During the nine months ended September 30, 2023, 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, 2022 (filed on March 1, 2023).

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 nine months ended September 30, 2023, 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, 2022 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, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2023.

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 and negative operating cash flows for the near future. The Company had a net loss of $356.8 million for the nine months ended September 30, 2023 and an accumulated deficit of $2.3 billion as of September 30, 2023. As of September 30, 2023, the Company had $668.7 million in cash, cash equivalents, and restricted cash, $267.8 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”). As of September 30, 2023, 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. 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 develop and commercialize future products and invest in the growth of its business and, consequently, will need to generate additional revenues to achieve future profitability and will 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 at all, 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 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 ASU 2017-01. 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 Natera common shares, 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 will be revalued at each reporting date and amount of compensation expense will be 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 Natera common stock.

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. In November 2022, the Company completed an underwritten equity offering and sold 13,144,500 shares of its common stock at a price of $35 per share to the public. Before estimated offering expenses of $0.5 million, the Company received proceeds of approximately $433.2 million net of the underwriting discount.

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 November 8, 2023.

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, average selling price expected to be received from payors, the discount rate impacting the operating right-of-use assets and the associated lease liabilities, the average useful life for property and equipment, 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. 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.

Revenue

The total consideration which the Company expects to be entitled to receive from patients and insurance carriers in exchange for the Company's products is a significant estimate determined by calculating the average selling price based on the contractual pricing agreed to with each insurance carrier for each test (CPT code) performed adjusted for variable consideration related to historical percent of cases allowed, historical percent of patient responsibility collected, and historical percent of contract price collected from insurance carriers. The Company uses the expected-value approach of estimating variable consideration.  The Company also considers recent 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 with similar reimbursement characteristics, the Company uses a portfolio approach to estimate the effects of variable consideration. The Company also applies a constraint to the estimated variable consideration when it assesses 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.

Allowance for doubtful accounts

The allowance for doubtful accounts for trade accounts receivable is based on the Company’s assessment of the collectability of accounts related to our 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 the three and nine months ended September 30, 2023 and 2022. The Company currently does not have an incremental 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. 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.

Investments and financial instruments

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.  

Other accrued liabilities

The Company's uses estimates, judgments, and assumptions in several areas including, but not limited to, estimates of progress to date for certain contracts with vendors, liabilities related to clinical trials, payroll and related expenses, marketing liabilities, reserves associated with insurance and general overpayments, tax-related liabilities, and other operating expenses. Estimates consist of historical trends, analytical procedures, review of supporting documentation, inquiries with supply partners and vendors, and other relevant assumptions. Although the Company believes its estimates, assumptions, and judgment are reasonable, they are based upon information presently available and are subject to change.

Credit Losses

Appropriate provision has been made for lifetime expected credit losses in accordance with ASC Topic 326-20, Financial Instruments—Credit Losses (“Topic 326”), for trade receivables and available-for-sale debt securities. The Company’s estimate of expected credit losses includes consideration of past events, current conditions, and forecasts of future economic conditions. The Company currently does not have a credit loss reserve against accounts receivable for insurance and patient payors due to the average selling price calculations which incorporate these risks as net receivables are recorded.  

Available-for-sale debt securities. The amended guidance from ASU 2016-13 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.

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.

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, which represents 5.25% of MyOme on a fully diluted basis. The Company does not hold a seat on MyOme’s board of directors. The Company’s investment in MyOme is recorded at cost and no impairment was identified as of September 30, 2023. The following are the Company’s related persons and the basis of each such related person’s relationship with MyOme:

● Matthew Rabinowitz, the Company’s executive chairman and co-founder, is the chairman of the board and founder of MyOme, and a beneficial holder of approximately 28.6% of the outstanding shares of MyOme on a fully dilutive basis;

● Jonathan Sheena, the Company’s co-founder and a member of the Company’s board of directors, is a stockholder and a member of the board of directors of Myome;

● Daniel Rabinowitz, the Company’s Secretary and Chief Legal Officer, is a stockholder of Myome; and

● Roelof Botha, the Lead Independent Director of the Company’s board of directors, is a managing member of Sequoia Capital. Certain funds affiliated with Sequoia Capital also participated in MyOme’s series B financing.

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.

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).

Risk and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash, cash equivalents, 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.

The Company performs evaluations of financial conditions for insurance carriers, patients, clinics and laboratory partners and generally does not require collateral to support credit sales. For the three and nine months ended September 30, 2023, and 2022, there were no payors or customers exceeding 10% of total revenues on an individual basis. As of September 30, 2023 and December 31, 2022, there were no payors or customers with an outstanding balance exceeding 10% of net accounts receivable. 

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.

Ending balance	$	(5,396)	$	(19,609)	$	(5,396)	$	(19,609)

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 losses was not necessary.

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. The Company does not expect adoption of this standard to have a material 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 from contracts with insurance carriers, laboratory partners and patients in connection with sales primarily related to prenatal genetic tests. The Company enters into contracts with insurance carriers with primarily payment terms related to tests provided to the 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.

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 (“WES”) services and the testing of patient samples to detect cancer mutations using its Signatera test. Each test is billable to customers 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. The Company allocates the contract price to each test using the stand-alone selling price for each service and recognizes the test processing revenue as individual test results are delivered to customers.

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 insurance carriers, 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, discounts, refunds and doubtful accounts, and is estimated using the expected value approach. For insurance carriers 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 insurance carriers, 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 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. Tests billed to insurance carriers and directly to patients usually takes an average of 18 months to fully collect the amounts estimated at delivery, and for tests billed to laboratory distribution partners, the average collection cycle takes approximately two to three months. At times, 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. Collection of cash attributable to such product revenue takes an average of 18 months to fully collect the amounts estimated at delivery and 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 September 30, 2023 and 2022, the Company increased revenue by a net of $2.2 million and $5.9 million, respectively, for tests delivered in prior periods that were fully collected, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by

$0.02 and $0.06, respectively. During the nine months ended September 30, 2023, the Company reduced revenue by a net of $3.7 million for tests delivered in prior periods, which decreased revenue and increased net loss by a corresponding amount and increased loss per share by $0.03. During the nine months ended September 30, 2022, the Company increased revenue by a net of $16.5 million for tests delivered in prior periods, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by $0.17.

Product revenue is constrained via refunds estimated to be paid to insurance carriers. Such 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 September 30, 2023 and 2022, the reserves for refunds to insurance carriers were reduced and product revenue increased by $1.2 million and $1.6 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 and $0.02 for the three months ended September 30, 2023 and 2022, respectively. During the nine months ended September 30, 2023 and 2022, the reserves for refunds to insurance carriers were reduced and product revenue increased by $7.7 million and $4.0 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 $0.07 and $0.04 for the nine months ended September 30, 2023 and 2022, respectively.

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 IVD kits. The Company also recognizes revenues from its strategic collaboration agreements, such as those with BGI Genomics Co., Ltd. and Foundation Medicine, Inc. The Company recognizes licensing revenue 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.

BGI Genomics

In February 2019, the Company entered into a License Agreement (the “BGI Genomics Agreement”) with BGI Genomics to develop, manufacture, and commercialize NGS-based genetic testing assays for clinical and commercial use. The BGI Genomics Agreement has a term of ten years and expires in February 2029. Pursuant to the BGI Genomics Agreement, the Company licensed its intellectual property to and will provide development services for BGI. Following completion of development services, the Company will provide assay interpretation services over the term of the agreement. Revenue associated with these performance obligations was recognized over time using the input method, based on costs incurred to perform the development services, since the level of costs incurred over time best reflect the transfer of development services. Revenue associated with the assay interpretation services will be recognized upon delivery of these services. Funds received in advance are recorded as deferred revenue and will be recognized as the related services are delivered.

In accordance with ASC 340-40, any incremental costs incurred to obtain a contract with a customer are required to be capitalized and amortized over the period in which the goods and services are transferred to the customer. The incremental costs incurred in connection with the BGI Genomics arrangement are not material on an accumulated basis and therefore have not been capitalized but have been expensed as incurred.

The initial transaction price was primarily comprised of license and milestone fees. 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. Certain milestone and license fees were constrained and not included in the transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The allocation of the transaction price was performed based on standalone selling prices, which are based on estimated amounts that the Company would charge for a performance obligation if it were sold separately.

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 NIPT and Oncology products, representing two separate performance obligations, to which $24.0 million of transaction consideration was allocated. Of this amount, $0.1 million and $7.3 million were recognized in the nine months ended September 30, 2023 and 2022, respectively. This performance obligation was fully satisfied in March 2023 and no further related amounts will be recognized as revenue.

As of September 30, 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 nine months ended September 30, 2023, the Company recognized $1.1 million related to oncology assay interpretation services, of which $0.7 million was recognized against deferred royalties. None was recognized in 2022. The Company currently has $19.3 million in deferred revenue as of September 30, 2023.

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 Condensed Consolidated Balance Sheet and will be periodically assessed for impairment. During the year ending December 31, 2022, $4.0 million was reclassified as prepaid expenses and other current assets. During the three and nine months ended September 30, 2023, $1.4 million and $4.0 million in equipment and services was received, respectively, which brought the remaining advanced payments to $6.0 million, with $1.1 million recorded in prepaid expenses and other current assets and $4.9 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 Foundation Medicine Agreement has an initial term of five years, expiring in August 2024, with automatic renewals thereafter for successive one-year terms, unless the Foundation Medicine Agreement is earlier terminated in accordance with its terms. Natera and Foundation Medicine will share the revenues generated from both biopharmaceutical and clinical customers in accordance with the terms of the Foundation Medicine Agreement.

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. Revenues associated with each of the performance obligations are recognized over time using the input method, based on costs incurred to perform the development services, since the level of costs incurred over time best reflect the transfer of development services. Revenue associated with the assay testing services will be recognized upon delivery of these services. Funds received in advance are recorded as deferred revenue and will be recognized as the related services are delivered.

The initial transaction price was primarily comprised of license and milestone fees. 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. Certain milestone fees were constrained and not included in the transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The allocation of the transaction price was performed based on standalone selling prices, which are based on estimated amounts that the Company would charge for a performance obligation if it were sold separately.

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 and $2.9 million was recognized in the nine months ended September 30, 2023 and 2022, respectively. 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 nine months ended September 30, 2023 and 2022, the Company recognized $0.3 million and $0.1 million, respectively, related to oncology assay interpretation services. The Company currently has $3.9 million in deferred revenue as of September 30, 2023.

Fair Value Measurements

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:

(1) Per the Company’s investment policy, all debt securities are classified as short-term investments irrespective of holding period.  

(2) Cash equivalents includes money market deposits and liquid demand deposits.

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 nine months ended September 30, 2023, the Company did not 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 September 30, 2023, the Company had 38 investments in an unrealized loss position in its portfolio. An allowance for credit losses was not necessary as the decrease in the fair market value for a majority of these available-for-sale securities was as a result of a significant average yield rate increase for similar securities as of September 30, 2023. The Company has assessed the unrealized loss position for available-for-sale debt securities for which an allowance for credit losses has not been recorded and concluded any such losses are temporary and not indicative of an impairment as these investments will be held until maturity or price recovery.

The following table presents debt securities available-for-sale that were in an unrealized loss position as of September 30, 2023, aggregated by major security type in a continuous loss position. There were no debt securities available-for-sale in an unrealized loss position for less than 12 months as of September 30, 2023.

Operating Leases

In September 2015, the Company’s subsidiary 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 includes two 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 of two 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. The term of this lease is approximately 84 months and expires in October 2023. This lease contains an option to renew the lease term for five years, but the fair market rent amount upon renewal is not available from the landlord. 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 will be $9.3 million commencing 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 for five 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 by three 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 will be used for laboratory and research use and is expected to commence 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 starts 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 approximating one to five 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 nine months ended September 30, 2023, the Company had $0.1 million in noncash operating activities related to additional right-of-use assets accounted for exercising the option to extend a lease under ASC 842. For the nine months ended September 30, 2022, the Company had noncash operating activities of $22.1 million primarily related to additional right-of-use assets related to the Austin First and Second Expansion Premises commenced in February 2022 and September 2022, respectively, which was accounted for as a new lease under ASC 842.

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:

	September 30,		December 31,
	2023		2022
		(in thousands)
Operating lease liabilities, current portion included in other accrued liabilities	$	11,038	$	7,639
Operating lease liabilities, long-term portion		68,287		76,577
Total operating lease liabilities	$	79,325	$	84,216

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 September 30, 2023, the weighted-average remaining lease term was 6.94 years and the weighted-average discount rate was 6.67%.

The Company continues to recognize lease expense on a straight-line basis. The lease expense includes the amortization of the right-of-assets with the associated interest component estimated by applying the effective interest method. For the three months ended September 30, 2023 and 2022, total lease expense of $3.6 million and $3.5 million was recognized in the condensed statements of operations and comprehensive loss, respectively. For the nine months ended September 30, 2023 and 2022, total lease expense of $11.0 million and $10.0 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 $3.2 million and $1.7 million for the three months ended September 30, 2023 and 2022, respectively. Cash paid for amounts in the measurement of operating lease liabilities totaled $8.4 million and $7.2 million for the nine months ended September 30, 2023 and 2022, respectively.

The present value of the future annual minimum lease payments under all non-cancellable operating leases as of September 30, 2023 are as follows:

	Operating Leases

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.

An independent committee of the Company’s board of directors initiated and has completed an internal investigation into the allegations made in a March 2022 short seller report, with the assistance of the law firm of WilmerHale LLP. WilmerHale had access to company executives, personnel, records, communications, and documents. Based on the investigation, the independent committee, on behalf of the board, has concluded that the allegations of wrongdoing against the Company in the report were unfounded.

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 the financial statements.  

Intellectual Property Litigation Matters.

The Company has been involved in two 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 (“Stanford”) 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 all three 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 alleges, in suits filed in January 2020 and May 2022, infringement by CareDx of three of the Company’s patents, seeking unspecified damages and injunctive relief. The case is currently pending and is scheduled for trial in January 2024.

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 Corp. (“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. A jury trial was held in May 2023, after which the jury returned a verdict in favor of the Company, finding all three asserted patents valid and infringed by ArcherDX and

Invitae and awarding damages totaling $19.35 million to the Company. A bench trial was held in June 2023 on defendants’ remaining equitable defense against two of the Natera patents; the court issued an order denying the defendants’ equitable defense in September 2023. Also in June 2023, the Company moved for a permanent injunction against the PCM test, which motion remains pending before the court. The court has entered an interim judgment in favor of the Company pursuant to the May 2023 jury verdict and the September 2023 court order. ArcherDX and Invitae have filed post-trial motions in response to the interim judgment. The Company intends to oppose the motions.

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 of two Ravgen patents. The complaint seeks monetary damages and injunctive relief. Various parties, including Natera, 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. The lawsuit is currently scheduled for trial in January 2024.

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 infringe one 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 January 2021, the Company filed suit against Inivata, Inc. and Inivata Ltd. (collectively “Inivata”) in the United States District Court for the District of Delaware. The complaint, amended by the Company in May 2021, alleges that various Inivata oncology products infringe two of the Company’s patents and seeks unspecified monetary damages and injunctive relief. Inivata filed a motion to dismiss the Company’s amended complaint, which the Court denied. In December 2022, the Company filed a second suit against Inivata in the same district court, alleging that certain of Inivata’s oncology products additionally infringe a third patent of the Company’s, and seeking unspecified monetary damages and injunctive relief. The two suits have been consolidated. Inivata has filed a motion to dismiss the Company’s second complaint, which motion is currently pending before the Court.

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. Trial is currently scheduled for March 2024.

In July 2023, the Company filed suit against NeoGenomics Laboratories, Inc. (“NeoGenomics”) in the United States District Court for the Middle District of North Carolina, alleging infringement of certain Natera patents by NeoGenomics’ commercialization of the RaDaR test. The complaint seeks monetary damages and injunctive relief. The Company filed a motion for preliminary injunction, which is pending before the Court.

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 Natera 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. On July 17, 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 Natera, ruling that CareDx is not entitled to any damages. Both parties have filed notices of appeal.

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 March 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, to which the Company expects to file a response.

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 October 2023, a shareholder derivative complaint was filed in the United States District Court for the Western District of Texas against the Company as nominal defendant and certain of the Company’s management, alleging, 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.

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 September 30, 2023 with a remaining term of at least one year:

Stock-Based Compensation

9. Stock-Based Compensation

2015 Equity Incentive Plan

General.  The Company’s board of directors adopted its 2015 Equity Incentive Plan (the “2015 Plan”) in June 2015. The 2015 Plan replaced the Company’s prior stock plans.

Share Reserve.  The initial number of shares of the Company’s common stock available for issuance under the 2015 Plan was 3,451,495 shares. The number of shares reserved for issuance under the 2015 Plan will be increased automatically on the first business day of each fiscal year, commencing in 2016, by a number equal to the least of:

● 3,500,000 shares;

● 4% of the shares of common stock issued and outstanding on the last business day of the prior fiscal year; or

● a number of shares determined by the Company’s board of directors.

Stock options vest as determined by the compensation committee. In general, they will vest over a four-year period following the date of grant. Stock options expire at the time determined by the compensation committee but in no event more than ten years after they are granted. These awards generally expire earlier if the participant's service terminates earlier.

Restricted Shares and Stock Units.  Restricted shares and stock units (“RSUs”) may be awarded under the 2015 Plan in return for any lawful consideration, and participants who receive restricted shares or stock units generally are not required to pay cash for their awards. In general, these awards will be subject to vesting. Vesting may be based on length of service, the attainment of performance-based milestones or a combination of both, as determined by the compensation committee.

Employee Stock Purchase Plan

During the period ended September 30, 2023, there have not been any changes to the Company’s 2015 Natera, Inc. Employee Stock Purchase Plan (the “ESPP”) as disclosed in Form 10-K for the fiscal year ended December 31, 2022.  

The Company has made 3,964,612 shares available for issuance under the Plan as of September 30, 2023, a number that is automatically increased on the first business day of each fiscal year of the Company during the term of the ESPP by the least of (i) 1% of the total number of shares of common stock actually issued and outstanding on the last business day of the prior fiscal year, (ii) 880,000 shares of common stock (subject to the ESPP), or (iii) a number of shares of common stock determined by the Company’s board of directors.

The first offering period of 2023 started on November 1, 2022 and ended on April 30, 2023. As of September 30, 2023, 218,649 shares have been purchased in the first offering period. The second offering period of 2023 began on May 1, 2023 and ended on October 31, 2023.

Performance-based Awards

The Company grants certain senior-level executives performance stock options and units which vest based on either market and time-based service conditions or performance and time-based service conditions, which are referred to herein as performance-based awards. The Company assessed the performance-based awards with the appropriate valuation method and has recognized the applicable stock-based compensation expense.

The Company has recognized $23.0 million and $12.4 million in stock-based compensation for performance-based awards for the three months ended September 30, 2023 and 2022, respectively. The Company has recognized $40.5 million and $40.0 million in stock-based compensation for performance-based awards for the nine months ended September 30, 2023 and 2022, respectively. There were no performance-based awards with market conditions and a fair value estimated using a Monte Carlo simulation model granted in the nine months ended September 30, 2023 and 2022.

Restricted Stock Units

The following table summarizes unvested RSU for the nine months ended September 30, 2023:

		Weighted-
		Average
		Grant Date
(in thousands, except for grant date fair value)	Shares	Fair Value
Balance at December 31, 2022	6,836	$	57.12

Vested	(2,364)	$	57.01
Cancelled/forfeited	(760)	$	50.01
Balance at September 30, 2023	9,440	$	50.28

Stock-Based Compensation Expense

Stock based compensation is related to stock options and RSUs granted to the Company’s employees and is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period of the respective awards on a straight-line basis. If awards have both a service condition and performance or market condition, then an accelerated expense method is used. No compensation cost is recognized when the requisite service has not been met and the awards are therefore forfeited.

Employee stock-based compensation expense is calculated based on awards ultimately expected to vest and has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates. Non-employee stock-based compensation expense is not adjusted for estimated forfeitures up until the occurrence of the actual forfeiture of the associated awards.

The following tables present the effect of employee and non-employee stock-based compensation expense on selected statements of operations line items for the three and nine months ended September 30, 2023 and 2022.

	Three months ended September 30,

As of September 30, 2023, approximately $368.4 million of unrecognized compensation expense, adjusted for estimated forfeitures, related to unvested option awards and RSUs will be recognized over a weighted-average period of approximately 2.5 years.

Valuation of Stock Option Grants to Employees and Non-employees

The Company utilizes the Black-Scholes option pricing model when estimating the fair value of stock options. For the three and nine months ended September 30, 2023, the following valuation assumptions were applied on both the employee and non-employee options.

	Three months ended September 30,						Nine months ended September 30,
	2023			2022			2023					2022
Expected term (years)		6.03			6.05		5.20		—	6.03		5.12		—	10.00
Expected volatility		68.23	%		61.63	%	68.23	%	—	70.07	%	55.91	%	—	62.30	%
Expected dividend rate		—	%		—	%				—	%				—	%
Risk-free interest rate		4.18	%		3.15	%	3.41	%	—	4.18	%	1.62	%	—	3.15	%

As of September 30, 2023, total stock options outstanding include stock options for 23,005 shares of common stock that were granted to non-employees, of which none are vested. Stock-based compensation expense related to stock options granted to non-employees is recognized as the stock option is earned and the services are rendered. The Company believes that the estimated fair value of the stock options is more readily measurable than the fair value of the services rendered.

Credit Line Agreement

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 September 30, 2023 was 6.53%. 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. 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. As of September 30, 2023, 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 October 2023, the interest rate for the Credit Line was subsequently changed to the 30-day SOFR average, plus 0.5%.

For the three months ended September 30, 2023 and 2022, the Company recorded interest expense on the Credit Line of $1.3 million and $0.4 million, respectively. For the nine months ended September 30, 2023 and 2022, the Company recorded interest expense on the Credit Line of $3.7 million and $0.8 million, respectively. Interest payments on the Credit Line were made within the same periods. As of September 30, 2023 and December 31, 2022, the total principal amount outstanding with accrued interest was $80.4 million.

Convertible Notes

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. The Company used approximately $79.2 million of the net proceeds from the Convertible Notes offering to repay its obligations under the 2017 Term Loan with OrbiMed.

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:  

● During any fiscal quarter commencing after March 31, 2020 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day.

● During the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Notes for each trading day of that five-day consecutive trading period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day.

● If the Company calls any or all of the Convertible Notes for redemption at any time prior to the close of business on the second business day prior to the redemption date.

● Upon the occurrence of certain distributions.

● Upon the occurrence of specified corporate transactions.

The first two circumstances have been met as of September 30, 2023. However, there were no conversions for the period ending September 30, 2023.

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, 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 its seven-year term. The outstanding Convertible Notes balances as of September 30, 2023 and December 31, 2022 are summarized in the following table:

11. Income Taxes

During the three months ended September 30, 2023 and 2022, the Company recorded total income tax expense of approximately $202,000 and $185,000, respectively. During the nine months ended September 30, 2023 and 2022, the Company recorded total income tax expense of approximately $80,000 and $557,000, respectively. The income tax expense is primarily attributable to state income tax and foreign income tax expenses resulting from testing to clinics and licenses of cloud-based software and intellectual property that are based in a foreign country. 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 September 30, 2023. 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 September 30, 2023 and December 31, 2022, there were no accrued interest and penalties related to uncertain tax positions.

12. Net Loss per Share

The Convertible Notes are convertible by the holders as of September 30, 2023. 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 shares issued to settle the Convertible Notes would exceed the Convertible Note principle by $105.7 million based on the closing price of the Company’s common stock as of September 30, 2023. 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 September 30, 2023 and 2022:

Summary of Significant Accounting Policies

Basis of Presentation

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 nine months ended September 30, 2023, 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, 2022 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, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2023.

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

Liquidity Matters

Liquidity Matters

The Company has incurred net losses since its inception and anticipates net losses and negative operating cash flows for the near future. The Company had a net loss of $356.8 million for the nine months ended September 30, 2023 and an accumulated deficit of $2.3 billion as of September 30, 2023. As of September 30, 2023, the Company had $668.7 million in cash, cash equivalents, and restricted cash, $267.8 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”). As of September 30, 2023, 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. 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 develop and commercialize future products and invest in the growth of its business and, consequently, will need to generate additional revenues to achieve future profitability and will 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 at all, 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 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 ASU 2017-01. 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 Natera common shares, 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 will be revalued at each reporting date and amount of compensation expense will be 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 Natera common stock.

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. In November 2022, the Company completed an underwritten equity offering and sold 13,144,500 shares of its common stock at a price of $35 per share to the public. Before estimated offering expenses of $0.5 million, the Company received proceeds of approximately $433.2 million net of the underwriting discount.

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 November 8, 2023.

Principles of Consolidation

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

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, average selling price expected to be received from payors, the discount rate impacting the operating right-of-use assets and the associated lease liabilities, the average useful life for property and equipment, 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. 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.

Revenue

The total consideration which the Company expects to be entitled to receive from patients and insurance carriers in exchange for the Company's products is a significant estimate determined by calculating the average selling price based on the contractual pricing agreed to with each insurance carrier for each test (CPT code) performed adjusted for variable consideration related to historical percent of cases allowed, historical percent of patient responsibility collected, and historical percent of contract price collected from insurance carriers. The Company uses the expected-value approach of estimating variable consideration.  The Company also considers recent 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 with similar reimbursement characteristics, the Company uses a portfolio approach to estimate the effects of variable consideration. The Company also applies a constraint to the estimated variable consideration when it assesses 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.

Allowance for doubtful accounts

The allowance for doubtful accounts for trade accounts receivable is based on the Company’s assessment of the collectability of accounts related to our 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 the three and nine months ended September 30, 2023 and 2022. The Company currently does not have an incremental 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. 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.

Investments and financial instruments

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.  

Other accrued liabilities

The Company's uses estimates, judgments, and assumptions in several areas including, but not limited to, estimates of progress to date for certain contracts with vendors, liabilities related to clinical trials, payroll and related expenses, marketing liabilities, reserves associated with insurance and general overpayments, tax-related liabilities, and other operating expenses. Estimates consist of historical trends, analytical procedures, review of supporting documentation, inquiries with supply partners and vendors, and other relevant assumptions. Although the Company believes its estimates, assumptions, and judgment are reasonable, they are based upon information presently available and are subject to change.

Credit Losses

Credit Losses

Appropriate provision has been made for lifetime expected credit losses in accordance with ASC Topic 326-20, Financial Instruments—Credit Losses (“Topic 326”), for trade receivables and available-for-sale debt securities. The Company’s estimate of expected credit losses includes consideration of past events, current conditions, and forecasts of future economic conditions. The Company currently does not have a credit loss reserve against accounts receivable for insurance and patient payors due to the average selling price calculations which incorporate these risks as net receivables are recorded.  

Available-for-sale debt securities. The amended guidance from ASU 2016-13 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.

Investments

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.

Related Party

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, which represents 5.25% of MyOme on a fully diluted basis. The Company does not hold a seat on MyOme’s board of directors. The Company’s investment in MyOme is recorded at cost and no impairment was identified as of September 30, 2023. The following are the Company’s related persons and the basis of each such related person’s relationship with MyOme:

● Matthew Rabinowitz, the Company’s executive chairman and co-founder, is the chairman of the board and founder of MyOme, and a beneficial holder of approximately 28.6% of the outstanding shares of MyOme on a fully dilutive basis;

● Jonathan Sheena, the Company’s co-founder and a member of the Company’s board of directors, is a stockholder and a member of the board of directors of Myome;

● Daniel Rabinowitz, the Company’s Secretary and Chief Legal Officer, is a stockholder of Myome; and

● Roelof Botha, the Lead Independent Director of the Company’s board of directors, is a managing member of Sequoia Capital. Certain funds affiliated with Sequoia Capital also participated in MyOme’s series B financing.

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.

Fair Value

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).

Risk and Uncertainties

Risk and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash, cash equivalents, 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.

The Company performs evaluations of financial conditions for insurance carriers, patients, clinics and laboratory partners and generally does not require collateral to support credit sales. For the three and nine months ended September 30, 2023, and 2022, there were no payors or customers exceeding 10% of total revenues on an individual basis. As of September 30, 2023 and December 31, 2022, there were no payors or customers with an outstanding balance exceeding 10% of net accounts receivable. 

Accumulated Other Comprehensive Income (Loss)

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.

Ending balance	$	(5,396)	$	(19,609)	$	(5,396)	$	(19,609)

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 losses was not necessary.

Recent Accounting Pronouncements

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. The Company does not expect adoption of this standard to have a material impact on its consolidated financial statements.
