CareDx, Inc.
Notes to Unaudited Condensed Consolidated Financial Statements
1. ORGANIZATION AND DESCRIPTION OF BUSINESS
CareDx, Inc. (“CareDx” or the “Company”), together with its subsidiaries, is a leading precision medicine company focused on the discovery, development and commercialization of clinically differentiated, high-value diagnostic solutions for transplant patients and caregivers. The Company’s headquarters are in Brisbane, California. The primary operations are in Brisbane, California; Omaha, Nebraska; Fremantle, Australia; and Stockholm, Sweden.
The Company’s commercially available testing services consist of AlloSure® Kidney, a donor-derived cell-free DNA (“dd-cfDNA”) solution for kidney transplant patients, AlloMap® Heart, a gene expression solution for heart transplant patients, AlloSure® Heart, a dd-cfDNA solution for heart transplant patients, and AlloSure® Lung, a dd-cfDNA solution for lung transplant patients. The Company has initiated several clinical studies to generate data on its existing and planned future testing services. In April 2020, the Company announced its first biopharma research partnership for AlloCell, a surveillance solution that monitors the level of engraftment and persistence of allogeneic cells for patients who have received cell therapy transplants. The Company also offers high-quality products that increase the chance of successful transplants by facilitating a better match between a donor and a recipient of stem cells and organs. In 2019, theThe Company began providingalso provides digital solutions to transplant centers following the acquisitions of Ottr Complete Transplant Management (“Ottr”) and XynManagement, Inc. (“XynManagement”), as well as the acquisitions of TransChart LLC (“TransChart”), MedActionPlan.com, LLC (“MedActionPlan”) and The Transplant Pharmacy, LLC (“TTP”) in 2021.2021 and HLA Data Systems, LLC ("HLA Data Systems") in January 2023.
Testing Services
AlloSure Kidney has been a covered service for Medicare beneficiaries since October 2017.2017 through a Local Coverage Determination (“LCD”) first issued by Palmetto MolDX (“MolDX”), which was formed to identify and establish coverage and reimbursement for molecular diagnostics tests, and adopted by Noridian Healthcare Solutions, the Company’s Medicare Administrative Contractor (“Noridian”). The Medicare reimbursement rate for AlloSure Kidney is currentlcurrently $2,841. y $2,841. AlloSure Kidney has received positive coverage decisions from several commercial payers, and is reimbursed by other private payers on a case-by-case basis.
AlloMap Heart has been a covered service for Medicare beneficiaries since January 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240. AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.
In October 2020, AlloSure Heartthe Company received a final Palmetto MolDxMolDX Medicare coverage decision for AlloSure Heart. In November 2020, Noridian Healthcare Solutions, the Company's Medicare Administrative Contractor, issued a parallel coverage policy granting coverage for AlloSure Heart when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.
On March 2, 2023, MolDX issued a new billing article, with an effective date of March 31, 2023, related to the LCD entitled Molecular Testing for Solid Organ Allograft Rejection (the “Billing Article”). Prior to the Billing Article’s effective date, MolDX informed the affected parties, including CareDx, that enforcement of the revised billing practices outlined in the Billing Article will not be implemented until June 30, 2023. MolDX informed CareDx that its automatic adjudication process would remain in place until June 30, 2023, though claims submitted prior to that date must comply with the applicable LCDs. On May 4, 2023, MolDX issued a revised new billing article with an effective date of March 31, 2023 (the “Revised Billing Article” and together with the Billing Article, the “Billing Articles”). The Revised Billing Article impacts Medicare coverage for AlloSure Kidney, AlloSure Heart and AlloMap Heart and requires certain companies, including CareDx, to implement new processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, especially as it relates to when tests are covered in the for-cause and surveillance contexts. MolDX has acknowledged, however, that the Billing Article is a change as it relates to billing more than one test during a single patient encounter. Noridian has not yet adopted the new Billing Articles.
Although the Company believes the Billing Articles are inconsistent with the LCDs, Noridian’s and MolDX’s responses to public comments explaining the intended scope of various LCDs, and medical necessity, the Company determined to pause its Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 to allow the Company further time to evaluate the implications of the Billing Article and update its billing processes for AlloSure Kidney tests by educating clinicians and working with centers to update CareDx’s test order forms to capture the new information required under the Billing Article. Accordingly, the Company did not submit claims for approximately 3,200 AlloSure Kidney tests for Medicare reimbursement for the period from March 7, 2023 through March 31, 2023 and did not recognize revenue on these claims in the first quarter of 2023 aggregating to approximately $8.9 million (the “Impacted March Tests”).
In the second quarter of 2023, the Company plans to submit claims for Medicare reimbursement for the Impacted March Tests, following the delivery by the Company of a letter to Noridian explaining, among other things, (i) the Company’s belief that the Billing Articles impose new restrictions on Medicare coverage for the CareDx tests from those contained in the existing LCDs, (ii) that the Company plans to submit claims for reimbursement for the Impacted March Tests for which the Company has not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (iii) that AlloSure Kidney orders with a date of service on or after March 31, 2023 for other indications outside the parameters of the Revised Billing Article, or where the reason for testing

is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Revised Billing Article.
CareDx continued the Medicare reimbursement submissions for AlloMap Heart or AlloSure Heart following the issuance of the Billing Articles. In addition, CareDx is considering informing Noridian that until Noridian adopts the Revised Billing Article, CareDx will continue to submit AlloSure Heart tests for reimbursement only when used in conjunction with AlloMap Heart. The Company is also considering informing Noridian that (i) until June 30, 2023, it plans to submit claims for reimbursement for AlloMap Heart and AlloSure Heart tests for which the Company has not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (ii) AlloSure Heart and AlloMap Heart orders placed on or after June 30, 2023 for other indications outside the surveillance and for-cause parameters of the Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Billing Articles.
AlloSure Kidney has received positive coverage decisions from several commercial payers, and is reimbursed by other private payers on a case-by-case basis.AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.
In May 2021 and March 2023, the Company purchased a minority investment of common stock in the biotechnology company Miromatrix Medical, Inc. (“Miromatrix”), for $5.0an aggregate amount of $5.1 million, and the investment is marked to market. Miromatrix works to eliminate the need for an organ transplant waiting list through the development of implantable engineered biological organs.

Clinical Studies
In January 2018, the Company initiated the Kidney Allograft Outcomes AlloSure Kidney Registry study (“K-OAR”), to develop additional data on the clinical utility of AlloSure Kidney for surveillance of kidney transplant recipients. K-OAR is a multicenter, non-blinded, prospective observational cohort study which has enrolled more than 1,700 renal transplant patients who will receive AlloSure Kidney long-term surveillance.
In September 2018, the Company initiated the Surveillance HeartCare™ Outcomes Registry (“SHORE”). SHORE is a prospective, multi-center, observational registry of patients receiving HeartCare for surveillance. HeartCare combines the gene expression profiling technology of AlloMap Heart with the dd-cfDNA analysis of AlloSure® Heart in one surveillance solution.

In February 2019, AlloSure® Lung became available for lung transplant patients through a compassionate use program while the test is undergoing further studies. In June 2020, the Company submitted an AlloSure Lung application to the Palmetto MolDx Technical Assessment program seeking coverage and reimbursement for Medicare beneficiaries.

In September 2019, the Company announced the commencement of the Outcomes of KidneyCare on Renal Allografts (“OKRA”) study, which is an extension of K-OAR. OKRA is a prospective, multi-center, observational, registry of patients receiving KidneyCare for surveillance. KidneyCare combines the dd-cfDNA analysis of AlloSure Kidney with the gene expression profiling technology of AlloMap Kidney and the predictive artificial intelligence technology of iBox for a multimodality surveillance solution. The Company has not yet made any applications to private payers for reimbursement coverage of AlloMap Kidney or KidneyCare.

record (“EMR”) systems providing patient surveillance management tools and outcomes data to transplant centers. XynManagement provides two unique solutions, XynQAPI software (“XynQAPI”) and XynCare. XynQAPI simplifies transplant quality tracking and Scientific Registry of Transplant Recipients ("SRTR") reporting. XynCare includes a team of transplant assistants who maintain regular contact with patients on the waitlist to help prepare for their transplant and maintain eligibility.
In September 2020, the Company launched AlloCare, a mobile app that provides a patient-centric resource for transplant recipients to manage medication adherence, coordinate with Patient Care Managers for AlloSure scheduling and measure health metrics.
In January 2021, the Company acquired TransChart. TransChart provides EMR software to hospitals throughout the U.S. to care for patients who have or may need an organ transplant. As part of the Company's acquisition of TransChart in January 2021, the Company acquired TxAccess, a cloud-based service that allows nephrologists and dialysis centers to electronically submit referrals to transplant programs, closely follow and assist patients through the transplant waitlist process, and ultimately, through transplantation.
In June 2021, the Company acquired the Transplant Hero patient application. The application helps patients manage their medications through alarms and interactive logging of medication events.
InAlso in June 2021, the Company entered into a strategic agreement with OrganX, which was amended in April 2022, with OrganX to develop clinical decision support tools across the transplant patient journey. Together, the Company and OrganX will develop advanced analytics that integrate AlloSure, the first transplant specific dd-cfDNA assay, with large transplant databases to provide clinical data solutions. This partnership delivers the next level of innovation beyond multi-modality by incorporating a variety of clinical inputs to create a universal composite scoring system. The Company has agreed to potential future milestone payments.
In November 2021, the Company acquired MedActionPlan, a New Jersey-based provider of medication safety, medication adherence and patient education. MedActionPlan is a leader in patient medication management for transplant patients and beyond.
In December 2021, the Company acquired TTP, a transplant focused pharmacy located in Mississippi. TTP provides individualized transplant pharmacy services for patients at multiple transplant centers located throughout the U.S.
COVID-19 Pandemic
The full impact of the continued COVID-19 pandemic, including the impact associated with preventative and precautionary measures that the Company, other businesses and governments have taken and may take, continues to evolve as of the date of this report. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company, but the pandemic may materially affect the Company's financial condition, liquidity and future results of operations.
In the final weeks of March and during April 2020, with hospitals increasingly caring for COVID-19 patients, hospital administrators chose to limit or even defer, non-emergency procedures. Immunosuppressed transplant patients either self-prescribed or were asked to avoid transplant centers and caregiver visits to reduce the risk of contracting COVID-19. As a result, with transplant surveillance visits down, the Company experienced a slowdown in testing services volumes in the final weeks of March and during April 2020. As a response to the COVID-19 pandemic, and to enable immune-compromised transplant patients to continue to have their blood drawn, in late March 2020, the Company launched RemoTraC, a remote
10

home-based blood draw solution using mobile phlebotomy for AlloSure and AlloMap surveillance tests, as well as for other standard monitoring tests.
There continues to be uncertainty around the COVID-19 pandemic as the Omicron variant, including its sub-variants, has caused an increase in COVID-19 cases globally, impacted the availability of medical personnel in transplant centers and the volume of transplant procedures. A sustained reduction in transplant volume can negatively impact the testing volumes, as the Company saw in the early part of the first quarter of 2022.
The Company's product business experienced a reduction in forecasted sales volume throughout the second and third quarters of 2020, as it was unable to undertake onsite discussions and demonstrations of its recently launched NGS products, including AlloSeq Tx 17, which was awarded CE mark authorization in May 2020. The Company's product business regained normalized sales volumes during the fourth quarter of 2020.
The Company is maintaining its testing, manufacturing, and distribution facilities while implementing specific protocols to reduce contact among employees. In areas where COVID-19 impacts healthcare operations, the Company's field-based sales and clinical support teams are supporting providers through virtual platforms. Although the executive orders that placed certain restrictions on operations in San Mateo County and the State of California, where the Company's laboratory and headquarters are located, were lifted effective June 15, 2021, new orders or restrictions could be adopted in the future depending upon the COVID-19 transmission rates in the Company's county and state, as well as other factors.
In addition, the Company created, and continues to have, a COVID-19 task force that is responsible for crisis decision making, employee communications, and enforcing all safety, monitoring and testing protocols in line with local regulations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The significant accounting policies and estimates used in preparation of the unaudited condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021,2022, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021,2022, filed with the Securities and Exchange Commission (the “SEC"SEC") on February 24, 2022.27, 2023. Material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 20212022 are reflected below.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and follow the requirements of the SEC for
11

Table of Contents
interim reporting. As permitted under those rules, certain notes and other financial information that are normally required by U.S. GAAP can be condensed or omitted. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair statement of the Company’s financial information. The condensed consolidated balance sheet as of December 31, 20212022 has been derived from audited consolidated financial statements as of that date but does not include all of the financial information required by U.S. GAAP for complete financial statements. Operating results for the three and nine months ended September 30, 2022March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.2023.
Use of Estimates
The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses in the unaudited condensed consolidated financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to transaction price estimates used for testing services revenue; standalone fair value of patient and digital solutions revenue performance obligations; accrued expenses for clinical studies; inventory valuation; the fair value of issued common stock warrants and embedded derivatives; the fair value of assets and liabilities acquired in a business combination or an assets acquisition (including identifiable intangible assets acquired); the fair value of contingent consideration recorded in connection with a business combination or an asset acquisition; the grant date fair value assumptions used to estimate stock-based compensation expense; income taxes; impairment of long-lived assets and indefinite-lived assets (including goodwill); and legal contingencies. Actual results could differ from those estimates.
Concentrations of Credit Risk and Other Risks and Uncertainties
For the three months ended September 30,March 31, 2023 and 2022, approximately 42% and 2021, approximately 53% and 61%, respectively, of total revenue was derived from Medicare. For the nine months ended September 30, 2022 and 2021, approximately 54% and 60%, respectively, of total revenue was derived from Medicare.
As of September 30, 2022March 31, 2023 and December 31, 2021,2022, approximately 30%26% and 27%, respectively, of accounts receivable was due from Medicare. No other payer or customer represented more than 10% of accounts receivable at either September 30, 2022March 31, 2023 or December 31, 2021.2022.
Marketable Securities
The Company considers all highly liquid investments in securities with a maturity of greater than three months at the time of purchase to be marketable securities. As of September 30, 2022,March 31, 2023, the Company’s short-term marketable securities consisted of corporate debt securities with maturities of greater than three months but less than twelve months at the time of purchase, which were classified as current assets on the condensed consolidated balance sheet.
The Company classifies its short-term marketable securities as held-to-maturity at the time of purchase and reevaluates such designation at each balance sheet date. The Company has the positive intent and ability to hold these marketable securities to maturity. Short-term marketable securities are carried at amortized cost and are adjusted for amortization of premiums and accretion of discounts to maturity, which is included inin interest income (expense), net on the condensed consolidated statements of operations. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on short-term marketable securities are included in interest income (expense), net. The cost of securities sold will be determined using specific identification.
The Company considers investments in securities with remaining maturities of over one year as long-term investments. As of September 30, 2022,March 31, 2023, the Company's long-term marketable securities consisted of corporate equity securities and corporate debt securities. TheThese long-term marketable securities are classified as other assets on the condensed consolidated balance sheet.sheet.

Table of Contents
The Company classifies its long-term marketable debt securities as available-for-sale and reevaluates such designation at each balance sheet date. Unrealized gains and losses from the reevaluation of the long-term marketable debt securities, if any, are included in other comprehensive gain (loss) in the condensed consolidated statement of comprehensive income (loss). Realized gains and losses and declines in value judged to be other-than-temporary, if any, on long-term marketable securities are included in interest income, net.
The Company records its long-term marketable equity securities at fair market value. Unrealized gains and losses from the remeasurement of the long-term marketable equity securities to fair value are included in other income (expense), net, in the condensed consolidated statements of operations.
Leases
The Company adopted Accounting Standard Codification (“ASC”) Topic 842, Leases and determines if an arrangement is or contains a lease at contract inception. A right-of-use (“ROU”) asset, representing the underlying asset during the lease term, and
12

Table of Contents
a lease liability, representing the payment obligation arising from the lease, are recognized on the condensed consolidated balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the ROU asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-termThe Company also has lease arrangements with lease and non-lease components. The Company elected the practical expedient not to separate non-lease components from lease components for the Company's facility leases. The Company also elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease liabilities are not recognized for leases with an initial term of 12 months or less are not recorded on the balance sheet.less.
The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its incremental borrowing rate. The incremental borrowing rate is determined by using the rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments for a similar term and in a similar economic environment.
As of September 30, 2022,March 31, 2023, the Company’s leases had remaining terms of 1.170.67 years to 10.359.85 years, some of which include options to extend the lease term.
Revenue
The Company recognizes revenue from testing services, product sales and patient and digital solutions revenue in the amount that reflects the consideration that it expects to be entitled in exchange for goods or services as it transfers control to its customers. Revenue is recorded considering a five-step revenue recognition model that includes identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations and recognizing revenue when, or as, an entity satisfies a performance obligation.
Testing Services Revenue
AlloSure Kidney, AlloMap Heart, AlloSure Heart and AlloSure Lung patient tests are ordered by healthcare providers. The Company receives a test requisition form with payer information along with a collected patient blood sample. The Company considers the patient to be its customer and the test requisition form to be the contract. Testing services are performed in the Company’s laboratory. Testing services represent one performance obligation in a contract and are performed when results of the test are provided to the healthcare provider, at a point in time.
The healthcare providers that order the tests and on whose behalf the Company provides testing services are generally not responsible for the payment of these services. The first and second revenue recognition criteria are satisfied when the Company receives a test requisition form with payer information from the healthcare provider. Generally, the Company bills third-party payers upon delivery of an AlloSure Kidney, AlloMap Heart, AlloSure Heart or AlloSure Lung test result to the healthcare provider. Amounts received may vary amongst payers based on coverage practices and policies of the payer. The Company has used the portfolio approach under Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers, to identify financial classes of payers. Revenue recognized for Medicare and other contracted payers is based on the agreed current reimbursement rate per test, adjusted for historical collection trends where applicable. The Company estimates revenue for non-contracted payers and self-payers using transaction prices determined for each financial class of payers using history of reimbursements. This includes analysis of an average reimbursement per test and a percentage of tests reimbursed. This estimate requires significant judgment.
The Company monitors revenue estimates at each reporting period based on actual cash collections in order to assess whether a revision to the estimate is required. Changes in transaction price estimates are updated quarterly based on actual cash collected or changes made to contracted rates.

On March 2, 2023, MolDX issued a new Billing Article, with an effective date of March 31, 2023. The Billing Article impacts Medicare coverage for AlloSure Kidney, AlloSure Heart and AlloMap and requires the Company to implement new processes to address requirements related to Medicare claim submissions. ASC 606-10-25-1 requires the Company to assess whether it is probable that it will collect substantially all of the consideration to which it will be entitled. Based upon the Company’s review of the Billing Article, it was determined to pause Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 that created uncertainty around the collection of the claims. Accordingly, the Company did not recognize revenue for approximately 3,200 AlloSure Kidney tests aggregating to $8.9 million for the three months ended March 31, 2023.
Product Revenue
Product revenue is recognized from the sale of products to end-users, distributors and strategic partners when all revenue recognition criteria are satisfied. The Company generally has a contract or a purchase order from a customer with the specified required terms of order, including the number of products ordered. Transaction prices are determinable and products are delivered and risk of loss passed to the customer upon either shipping or delivery, as per the terms of the agreement.
Patient and Digital Solutions Revenue
Patient and digital solutions revenue is mainly derived from a combination of software as a service ("SaaS") and perpetual software license agreements entered into with various transplant centers, which are the Company's customers for this class of revenue. The main performance obligations in connection with the Company's SaaS and perpetual software license agreement are the following: (i) implementation services and delivery of the perpetual software license are considered a single performance obligation, and (ii) post contract support. The Company allocates the transaction price to each performance obligation based on relative stand-alone selling prices of each distinct performance obligation. Digital revenue in connection with perpetual software license agreements is recognized over time based on the Company’s satisfaction of each distinct performance obligation in each agreement.
Perpetual software license agreements typically require advance payments from customers upon the achievement of certain milestones. The Company records deferred revenue in relation to these agreements when cash payments are received, or invoices are issued in advance of the Company’s performance, and generally recognizes revenue over the contractual term, as performance obligations are fulfilled.
In addition, the Company derives patient and digital solutions revenue from software subscriptions and medication sales. The Company generally bills software subscription fees in advance. Revenue from software subscriptions is deferred and recognized ratably over the subscription term. The medication sales revenue is recognized based on the negotiated contract price with the governmental, commercial and non-commercial payers with any applicable patient co-pay. The Company recognizes revenue from medication sales when prescriptions are delivered.

4. FAIR VALUE MEASUREMENTS
The Company records its financial assets and liabilities at fair value. The carrying amounts of certain financial instruments of the Company, including cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:
Level 1: Inputs that include quoted prices in active markets for identical assets and liabilities.
Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of September 30, 2022,During March 2023, the Company had onewrote off $1.0 million of its investment in convertible preferred shares from a private company which was carried at cost. InThis private company's operations are in the event the Company had to calculate theprocess of being liquidated. The fair value of this investment it would bewas based on Level 3 inputs.     This investment is not considered material to the Company's condensed consolidated financial statements.
In determining fair value, the Company uses various valuation approaches within the fair value measurement framework.  The valuation methodologies used for the Company’s instruments measured at fair value and their classification in the valuation hierarchy are summarized below:
Money market funds – Investments in money market funds are classified within Level 1. Money market funds are valued at the closing price reported by the fund sponsor from an actively traded exchange. At September 30, 2022March 31, 2023 and December 31, 2021,2022, money market funds were included as cash and cash equivalents in the condensed consolidated balance sheets.
Short-term marketable securities – Investments in short-term marketable securities are classified within Level 2. The securities are valued using third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly.
Long-term marketable equity and debt securities – Investments in long-term marketable equity securities are classified within Level 1. The securities are recorded at fair value based on readily available quoted market prices in active markets. Investments in long-term marketable debt securities are classified within Level 2. The securities are recorded at fair value based on observable inputs for quoted prices for identical or similar assets in markets that are not active. Long-term marketable securities are located within other assets on the condensed consolidated balance sheets.
Contingent consideration Contingent consideration is classified within Level 3. Contingent consideration relates to asset acquisitions and business combinations. The Company recorded the estimate of the fair value of the contingent consideration based on its evaluation of the probability of the achievement of the contractual
17

Table of Contents
conditions that would result in the payment of the contingent consideration. Contingent consideration was estimated using the fair value of the milestones to be paid if the contingency is met multiplied by management’s estimate of the probability of success at a discounted rate of 7% and 12% at September 30, 2022March 31, 2023 and December 31, 2021.2022, respectively. The significant input in the Level 3 measurement that is not supported by market activity is the Company’s probability assessment of the achievement of the milestones. The value of the liability is subsequently remeasured to fair value at each reporting date, and the change in estimated fair value is recorded as a component of operating expenses until the milestones are paid, expire or are no longer achievable. Increases or decreases in the estimation of the probability percentage result in a directionally similar impact to the fair value measurement of the contingent consideration liability. The carrying amount of the contingent consideration liability represents its fair value.
Common stock warrant liability – Common stock warrant liability is classified within Level 3. The Company utilizes intrinsic value to estimate the fair value of the warrants. The intrinsic value is computed as the difference between the fair value of the Company’s common stock on the valuation date and the exercise price of the warrants. Increases (decreases) in the Company's stock price discussed above result in a directionally similar impact to the fair value of the common stock warrant liability. Prior to fiscal year 2022, the Company utilized a binomial lattice pricing model (the “Monte Carlo Simulation Model”) which involves a market condition simulation to estimate the fair value of the warrants. The application of the Monte Carlo Simulation Model requires the use of a number of complex assumptions, including the Company’s stock price, expected life of the warrants, stock price volatility determined from the Company’s historical stock prices, and risk-free rates based on the implied yield currently available in the U.S. Treasury zero-coupon issues with a remaining term equal to the expected life of the warrants. The change in valuation method does not have material financial impact.

6. BUSINESS COMBINATIONS
The Transplant PharmacyHLA Data Systems
In December 2021,January 2023, the Company acquired TTP,HLA Data Systems, a transplant focused pharmacy located in Mississippi.Texas-based company that provides software and interoperability solutions for the histocompatibility and immunogenetics community. The Company acquired TTPHLA Data Systems with a combination of cash consideration paid upfront and contingent consideration with a fair value of $1.3 million. TTP provides individualized transplant pharmacy services for patients at multiple transplant centers located throughout the U.S.
The Company accounted for the transaction as a business combination using the acquisition method of accounting. Acquisition-related costs of $0.3 million were expensed as incurred, and classified as part of general and administrative expenses in the condensed consolidated statements of operations.
Goodwill of $5.5 million arising from the acquisition primarily consists of additional growth opportunities within the pharmacy sector. The integration of TTP into the Company’s portfolio is expected to continue to increase the transplant ecosystem for patients and make medication more accessible. The Company estimated net deferred tax liabilities of approximately $0.6 million arising from temporary differences related to the assets acquired and liabilities assumed. None of the goodwill is expected to be deductible for income tax purposes. All of the goodwill has been assigned to the Company’s existing operating segment.
The following table summarizes the fair value of the intangible asset acquired as of the acquisition date ($ in thousands):
Estimated Fair ValueEstimated Useful Life (Years)
Trademark$2,080 10
The trademark acquired consists primarily of the TTP brand and markings. The fair value of the trademark was determined using the relief-from-royalty method under the income approach. This method considers the value of the asset to be the value of the royalty payments from which the Company is relieved due to its ownership of the asset. The royalty rate of 2% was used to estimate the fair value of the trademark.
A discount rate of 13.5% was utilized in estimating the fair value of the trademark.
The pro forma impact of the TTP acquisition is not material, and the results of operations of the acquisition have been included in the Company's condensed consolidated statements of operations from the respective acquisition date.
MedActionPlan
In November 2021, the Company acquired MedActionPlan, a New Jersey-based provider of medication safety, medication adherence and patient education. The Company acquired MedActionPlan with a combination of cash consideration paid upfront and contingent consideration with a fair value of $3.5 million. MedActionPlan is a leader in patient medication management for transplant patients and beyond.
The Company accounted for the transaction as a business combination using the acquisition method of accounting. Acquisition-related costs of $0.6$0.4 million associated with the acquisition were expensed as incurred, and classified as part of general and administrative expenses in the condensed consolidated statement of operations.
Goodwill of $4.9$2.1 million arising from the acquisition primarily consists of synergies from integrating the MedActionPlanHLA Data Systems' technology with the current testing and digital solutions offered by the Company. The integrationacquisition of MedActionPlan into centers withHLA Data Systems will provide a robust and comprehensive Laboratory Information Management System and support the Company's other software platforms will continue to increase the standard of care for transplant patient safety, increase efficiency and facilitate medication compliance.laboratory workflows. None of the goodwill is expected to be deductible for income tax purposes. All of the goodwill has been assigned to the Company’s existing operating segment.

projected cash flows that are expected to be generated by the customer relationships, less charges representing the contribution of other assets to those cash flows that use projected cash flows with and without the intangible asset in place. The economic useful life was determined based on the distribution of the present value of the cash flows attributable to the intangible asset.
The acquired developed technology represents the fair value of MedActionPlan’sHLA Data Systems' proprietary software. The trademark acquired consists primarily of the MedActionPlanHLA Data Systems brand and markings. The fair value of both the developed technology and the trademark were determined using the relief-from-royalty method under the income approach. This method considers the value of the asset to be the value of the royalty payments from which the Company is relieved due to its ownership of the asset. The royalty rates of 15%10% and 1%2% were used to estimate the fair value of the developed technology and the trademark, respectively.
A discount rate of 40.0%24% was utilized in estimating the fair value of these three intangible assets.

The Company estimates the range of liability related to any pending litigation where the amount and range of loss can be estimated. The Company records its best estimate of a loss when the loss is considered probable.

2014 Employee Stock Purchase Plan
The Company has an Employee Stock Purchase Plan (the “ESPP”), under which employees can purchase shares of its common stock based on a percentage of their compensation, but not greater than 15% of their respective earnings; provided, however, an eligible employee’s right to purchase shares of the Company’s common stock may not accrue at a rate which exceeds $25,000 of the fair market value of such shares for each calendar year in which such rights are outstanding. The ESPP has consecutive offering periods of approximately six months in length. The purchase price per share must be equal to the lower of 85% of the fair value of the common stock on the first day of the offering period or on the exercise date.
During the offering period in 2022 that ended on June 30,December 31, 2022, 67,57047,025 shares were purchased pursuant to the ESPP for aggregate proceeds of $1.2 million from the issuance of such shares, which occurred on July 1, 2022.

No tax benefit was recognized related to stock-based compensation expense since the Company has never reported taxable income and has established a full valuation allowance to offset all of the potential tax benefits associated with its deferred tax assets.  In addition, no amounts of stock-based compensation expense were capitalized for the periods presented.
13. INCOME TAXES
The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses and other permanent differences between income before income taxes and taxable income. 
For the three and nine months ended September 30,March 31, 2023 and 2022, the Company recorded an income tax expense of $0.3$0.1 million and $0.2 million, respectively, compared to an income tax benefit of $0.2 million and $0.5 million for the three and nine months ended September 30, 2021,$12,000, respectively. The income tax expense of $0.3$0.1 million and $0.2 million for the three and nine months ended September 30, 2022, respectively, is primarily attributable to the state incomeU.S. current tax expense offset by the recognition of deferred tax assets from foreign losses.expense. The Company assesses the realizability of its net deferred tax assets by evaluating all available evidence, both positive and negative, including (i) cumulative results of operations in recent years, (ii) sources of recent losses, (iii) estimates of future taxable income, and (iv) the length of net operating loss carryforward periods. The Company believes that based on the history of its U.S. losses and other factors, the weight of available evidence indicates that it is more likely than not that it will not be able to realize its U.S. consolidated net deferred tax assets. The Company has also placed a valuation allowance on the net deferred tax assets of its AustralianSweden operations. Accordingly, the U.S. and AustralianSweden net deferred tax assets have been offset by a full valuation allowance.

Kidney
AlloSure Kidney, our transplant surveillance solution, was commercially launched in October 2017 and is our donor-derived cell-free DNA, or dd-cfDNA offering built on a next generation sequencing, or NGS, platform. In transplantation, more than 100 papers from over 50 studies globally have shown the value of dd-cfDNA in the management of solid organ transplantation. AlloSure Kidney is able to discriminate dd-cfDNA from recipient-cell-free DNA, targeting polymorphisms between donor and recipient. This single nucleotide polymorphism, or SNP, approach across all the somatic chromosomes is specifically designed for transplantation, allowing a scalable, high-quality test to differentiate dd-cfDNA.
AlloSure Kidney has received positivebeen a covered service for Medicare beneficiaries since October 2017 through a Local Coverage Determination, or LCD, first issued by Palmetto MolDX, or MolDX, which was formed to identify and establish coverage decisionsand reimbursement for reimbursement from Medicare.molecular diagnostics tests, and adopted by Noridian Healthcare Solutions, our Medicare Administrative Contractor, or Noridian. The Medicare reimbursement rate for AlloSure Kidney is currently $2,841.
On March 2, 2023, MolDX issued a new billing article, with an effective date of March 31, 2023, related to the LCD entitled Molecular Testing for Solid Organ Allograft Rejection, or the Billing Article. Prior to the Billing Article’s effective date, MolDX informed the affected parties, including CareDx, that enforcement of the revised billing practices outlined in the Billing Article will not be implemented until June 30, 2023. MolDX informed us that its automatic adjudication process would remain in place until June 30, 2023, though claims submitted prior to that date must comply with the applicable LCDs. On May 4, 2023, MolDX issued a revised new billing article with an effective date of March 31, 2023, or the Revised Billing Article, and together with the Billing Article, the Billing Articles. The Revised Billing Article impacts Medicare coverage for AlloSure Kidney, AlloSure Heart and AlloMap Heart and requires certain companies, including CareDx, to implement new processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, especially as it relates to when tests are covered in the for-cause and surveillance contexts.MolDX has acknowledged, however, that the Billing Article is a change as it relates to billing more than one test during a single patient encounter. Noridian has not yet adopted the new Billing Articles.
Although we believe the Billing Articles are inconsistent with the LCDs, Noridian’s and MolDX’s responses to public comments explaining the intended scope of various LCDs, and medical necessity, we determined to pause our Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 to allow us further time to evaluate the implications of the Billing Article and update our billing processes for AlloSure Kidney tests by educating clinicians and working with centers to update CareDx’s test order forms to capture the new information required under the Billing Article. Accordingly, we did not submit claims for approximately 3200 AlloSure Kidney tests for Medicare reimbursement for the period from March 7, 2023 through March 31, 2023 and did not recognize revenue on these claims in the first quarter of 2023 aggregating to approximately $8.9 million, or the Impacted March Tests.
In the second quarter of 2023, we plan to submit claims for Medicare reimbursement for the Impacted March Tests, following the delivery by us of a letter to Noridian explaining, among other things, (i) our belief that the Billing Articles impose new restrictions on Medicare coverage for the CareDx tests from those contained in the existing LCDs, (ii) that we plan to submit claims for reimbursement for the Impacted March Tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (iii) that AlloSure Kidney orders with a date of service on or after March 31, 2023 for other indications outside the parameters of the Revised Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Revised Billing Article. Although we plan to submit claims for Medicare reimbursement for the Impacted March Tests, there is a risk that the claims are denied or that any reimbursement of such claims is subject to forfeiture.
AlloSure Kidney has received positive coverage decisions from several commercial payers, and is reimbursed by other private payers on a case-by-case basis.
Multiple studies have demonstrated that significant allograft injury can occur in the absence of changes in serum creatinine. Thus, clinicians have limited ability to detect injury early and intervene to prevent long-term damage using this marker. While histologic analysis of the allograft biopsy specimen remains the standard method used to assess injury and differentiate rejection from other injury in kidney transplants, as an invasive test with complications, repetitive biopsies are not well tolerated. AlloSure Kidney provides a non-invasive test, assessing allograft injury that enables more frequent, quantitative and safer assessment of allograft rejection and injury status. Beyond allograft rejection, the assessment of molecular inflammation has

shown further utility in the assessment of proteinuria, the formation of De Novo donor specific antibodies, or DSAs, and as a surrogate predictive measure of estimated glomerular filtration rate, or eGFR, decline. Monitoring of graft injury through AlloSure Kidney allows clinicians to optimize allograft biopsies, identify allograft injury and guide immunosuppression management more accurately.

Since the analytical validation paper in the Journal of Molecular Diagnostics in 2016 before the commercial launch of AlloSure Kidney, there has been an increasing body of evidence supporting the use of AlloSure Kidney dd-cfDNA in the assessment and surveillance of kidney transplants. Bloom et al evaluated 102 kidney recipients and demonstrated that dd-cfDNA levels could discriminate accurately and non-invasively distinguish rejection from other types of graft injury. In contrast, serum creatinine has area under the curve of 50%, showing no significant difference between patients with and without rejection. Multiple publications and abstracts have shown AlloSure Kidney’s value in the management of BK viremia, as well as numerous pathologies that cause molecular inflammation and injury such as DSAs and eGFR decline. Most recently its utility in the assessment of T-cell mediated rejection (TCMR) 1A and borderline rejection was published in the American Journal of Transplant, or AJT, and the outcomes of 1,000 patients waswere published in Kidney International.
The prospective multicenter trial, the K-OAR study, has enrolled over 1,700 patients, with plans to survey patients with AlloSure Kidney for 3 years and provide further clinical utility of AlloSure Kidney in the surveillance of kidney transplant recipients.
KidneyCare
KidneyCare combines the dd-cfDNA analysis of AlloSure Kidney with the gene expression profiling technology of AlloMap Kidney and the predictive artificial intelligence technology of iBox in one surveillance solution. We have not yet made any applications to private payers for reimbursement coverage of AlloMap Kidney or iBox.
In September 2019, we announced the enrollment of the first patient in the OKRA study, which is an extension of the K-OAR study. OKRA is a prospective, multi-center, observational registry of patients receiving KidneyCare for surveillance. Combined with K-OAR, more than 3,000 patients will behave been enrolled into the study.
Heart
AlloMap Heart is a gene expression test that helps clinicians monitor and identify heart transplant recipients with stable graft function who have a low probability of moderate-to-severe acute cellular rejection. Since 2008, we have sought to expand the adoption and utilization of our AlloMap Heart solution through ongoing studies to substantiate the clinical utility and actionability of AlloMap Heart, secure positive reimbursement decisions from large private and public payers, develop and enhance our relationships with key members of the transplant community, including opinion leaders at major transplant centers, and explore opportunities and technologies for the development of additional solutions for post-transplant surveillance.
We believe the use of AlloMap Heart, in conjunction with other clinical indicators, can help healthcare providers and their patients better manage long-term care following a heart transplant, can improve patient care by helping healthcare providers avoid the use of unnecessary, invasive surveillance biopsies and may help to determine the appropriate dosage levels of immunosuppressants. In 2008, AlloMap Heart received 510(k) clearance from the U.S. Food and Drug Administration for marketing and sale as a test to aid in the identification of heart transplant recipients, who have a low probability of moderate/severe acute cellular rejection at the time of testing, in conjunction with standard clinical assessment.
AlloMap Heart has been a covered service for Medicare beneficiaries since January 1, 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240.
The Revised Billing Article impacts Medicare coverage for AlloMap Heart and requires certain companies, including CareDx, to implement new processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, though acknowledged that the Billing Article is a change as to its previous billing article, which provided coverage only where AlloSure Heart was used in conjunction with AlloMap Heart. As previously discussed, Noridian has not adopted the Billing Articles. We continued the Medicare reimbursement submissions for AlloMap Heart following the issuance of the new Billing Articles. In addition, we are considering informing Noridian that until Noridian adopts the Revised Billing Article, we will continue to submit AlloMap Heart tests for reimbursement only when used in conjunction with AlloSure Heart. We are also considering informing Noridian that (i) until June 30, 2023, we plan to submit claims for reimbursement for AlloMap Heart tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (ii) AlloMap Heart orders placed on or after June 30, 2023 for other indications outside the surveillance and for-cause parameters of the Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Billing Articles. AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.

In October 2020, we received a final Palmetto MolDx Medicare coverage decision for AlloSure Heart. In November 2020, Noridian Healthcare Solutions, our Medicare Administrative Contractor, issued a parallel coverage policy granting coverage when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.

Additionally, although we have submitted to Medicare AlloMap Heart and AlloSure Heart tests for March 2023 without confirming whether they meet the Revised Billing Article’s parameters, there is a risk that any reimbursement of such claims are subject to forfeiture.
We have also successfully completed several landmark clinical trials in the transplant field demonstrating the clinical utility of AlloMap Heart for surveillance of heart transplant recipients. We initially established the analytical and clinical validity of AlloMap Heart based on our Cardiac Allograft Rejection Gene Expression Observational (Deng, M. et al., Am J Transplantation 2006) study, which was published in the AJT. A subsequent clinical utility trial, Invasive Monitoring Attenuation through Gene Expression (Pham MX et al., N. Eng. J. Med., 2010), published in The New England Journal of Medicine, demonstrated that clinical outcomes in recipients managed with AlloMap Heart surveillance were equivalent (non-inferior) to outcomes in recipients managed with biopsies. The results of our clinical trials have also been presented at major medical society congresses. AlloMap Heart is now recommended as part of the ISHLT (InternationalInternational Society for Heart and Lung Transplantation)Transplantation, or ISHLT, guidelines.

HeartCare
HeartCare includes the gene expression profiling technology of AlloMap Heart with the dd-cfDNA analysis of AlloSure Heart in one surveillance solution. An approach to surveillance using HeartCare provides information from two complementary measures: (i) AlloMap Heart – a measure of immune activation, and (ii) AlloSure Heart – a measure of graft injury.
Clinical validation data from the Donor-Derived Cell-Free DNA-Outcomes AlloMap Registry (NCT02178943), or D-OAR, was published in the AJT in 2019. D-OAR was an observational, prospective, multicenter study to characterize the AlloSure Heart dd-cfDNA in a routine, clinical surveillance setting with heart transplant recipients. The D-OAR study was designed to validate that plasma levels of AlloSure Heart dd-cfDNA can discriminate acute rejection from no rejection, as determined by endomyocardial biopsy criteria.
HeartCare provides robust information about distinct biological processes, such as immune quiescence, active injury, acute cellular rejection and antibody mediated rejection. In September 2018, we initiated the SHORE study. SHORE is a prospective, multi-center, observational, registry of patients receiving HeartCare for surveillance. Patients enrolled in SHORE will be followed for 5 years with collection of clinical data and assessment of 5-year outcomes.
The most recent ISHLT guidelines published in 2022 reinforced their use of AlloMap Heart, and referenced the combined use of AlloSure Heart and AlloMap Heart for surveillance purposes.
Lung
In February 2019, AlloSure Lung became available for lung transplant patients through a compassionate use program while the test is undergoing further studies. One of these studies, launched in April 2020, is the ALARM study, or AlloSure Lung Allograft Remote Monitoring, with Johns Hopkins University, where the impact of AlloSure Lung combined with RemoTraC will beis being measured. AlloSure Lung applies proprietary NGS technology to measure dd-cfDNA from the donor lung in the recipient bloodstream to monitor graft injury. In June 2020, we submitted an application to the Palmetto MolDx Technology Assessment program seeking coverage and reimbursement for AlloSure Lung and since then we have been in active discussions with Palmetto. In October 2021, we launched AlloSure Lung as part of the CHEST 2021 Annual Meeting. We have gained early adoption with some commercial payers.
Cellular Therapy
In April 2020, we initiated a research partnership for AlloCell, a surveillance solution that monitors the level of engraftment and persistence of allogeneic cells for patients who have received cell therapy. AlloCell is being commercialized through research

COVID-19 Impact
In January 2023, we acquired HLA Data Systems, a Texas-based company that provides software and interoperability solutions for the final weeks of Marchhistocompatibility and during April 2020, with hospitals increasingly caring for COVID-19 patients, hospital administrators chose to limit or even defer, non-emergency procedures. Immunosuppressed transplant patients either self-prescribed or were asked to avoid transplant centers and caregiver visits to reduce the risk of contracting COVID-19. Asimmunogenetics community. HLA Data Systems is a result, with transplant surveillance visits down, we experienced a slowdown in testing services volumesleader in the final weeks of March and during April 2020. As a response to the COVID-19 pandemic, and to enable immune-compromised transplant patients to continue to have their blood drawn, in late March 2020, we launched RemoTraC, a remote home-based blood draw solution using mobile phlebotomylaboratory information management industry for AlloSure and AlloMap surveillance tests, as well as for other standard monitoring tests.

There continues to be uncertainty around the COVID-19 pandemic as the Omicron variant, including its sub-variants, has caused an increase in COVID-19 cases globally, impacted the availability of medical personnel in transplant centers and the volume of transplant procedures. A sustained reduction in transplant volume can negatively impact the testing volumes, as we saw in the early part of the first quarter of 2022.
Our product business experienced a reduction in forecasted sales volume throughout the second and third quarters of 2020, as we were unable to undertake onsite discussions and demonstrations of our recently launched NGS products, including AlloSeq Tx 17, which was awarded CE mark authorization in May 2020. Our product business regained normalized sales volumes during the fourth quarter of 2020.
We are maintaining our testing, manufacturing, and distribution facilities while implementing specific protocols to reduce contact among our employees. In areas where COVID-19 impacts healthcare operations, our field-based sales and clinical support teams are supporting providers through virtual platforms.
Although the executive orders that placed certain restrictions on operations in San Mateo County and the State of California, where our laboratory and headquarters are located, were lifted effective June 15, 2021, new orders or restrictions may be adopted in the future depending upon the COVID-19 transmission rates in our county and state, as well as other factors.
In addition, we created, and continue to have, a COVID-19 task force that is responsible for crisis decision making, employee communications, and enforcing all safety, monitoring and testing protocols in line with local regulations.
Due to COVID-19, quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns or other restrictions on the conduct of business operations could occur or could impact personnel at third-party suppliers in the United States and other countries, or the availability or cost of materials, and there may be disruptions in our supply chain. Any manufacturing supply interruption of materials could adversely affect our ability to conduct ongoing and future research and testing activities.
In addition, our clinical studies may be affected by the COVID-19 pandemic. Clinical site initiation and patient enrollment may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic or reduced staffing due to staff members contracting COVID-19. Some patients may not be able to comply with clinical study protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, the ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to, or become infected with, COVID-19, may adversely impact our clinical trial operations.human leukocyte antigen laboratories.
Financial Operations Overview
Revenue
We derive our revenue from testing services, products sales, patient and digital solutions revenues. Revenue is recorded considering a five-step revenue recognition model that includes identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations and recognizing revenue when, or as, an entity satisfies a performance obligation.
Testing Services Revenue
Our testing services revenue is derived from AlloSure Kidney, AlloMap Heart, AlloSure Heart and AlloSure Lung tests, which represented 82%80% and 84% of our total revenue for the three months ended September 30,March 31, 2023 and 2022, 83% of our total revenue for the nine months ended September 30, 2022, and 88% of our total revenue for each of the three and nine months ended September 30, 2021.respectively. Our testing services revenue depends on a number of factors, including (i) the number of tests performed; (ii) establishment of coverage policies by third-party insurers and government payers; (iii) our ability to collect from payers with whom we do not have positive coverage determination, which often requires that we pursue a case-by-case appeals process; (iv) our ability to recognize revenues on tests billed prior to the establishment of reimbursement policies, contracts or payment histories; and (v) how quickly we can successfully commercialize new product offerings.
We currently market testing servicesAlloSure Kidney has been a covered service for Medicare beneficiaries since October 2017 through a LCD first issued by MolDX, which was formed to healthcare providers through our direct sales force that targets transplant centersidentify and their physicians, coordinatorsestablish coverage and nurse practitioners as well as general nephrologists managing transplant recipients. The healthcare providers that order thereimbursement for molecular diagnostics tests, and on whose behalfadopted by Noridian. The Medicare reimbursement rate for AlloSure Kidney is currently $2,841. AlloMap Heart has been a covered service for Medicare beneficiaries since January 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240. In October 2020, we provide our testing services are generally not responsiblereceived a final MolDX Medicare coverage decision for AlloSure Heart. Noridian issued a parallel coverage policy granting coverage for AlloSure Heart when used in conjunction with AlloMap Heart, which became effective in December 2020.

processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, though acknowledged that the Billing Article is a change as to our previous billing article, which provided coverage only where AlloSure Heart was used in conjunction with AlloMap Heart. Noridian has not adopted the new Billing Articles.
Although we believe the Billing Articles are inconsistent with the LCDs, Noridian’s and MolDX’s responses to public comments explaining the intended scope of various LCDs, and medical necessity, we determined to pause our Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 to allow us further time to evaluate the implications of the Billing Article and update our billing processes for AlloSure Kidney tests by educating clinicians and working with centers to update CareDx’s test order forms to capture the new information required under the Billing Article. Accordingly, we did not submit claims for approximately 3200 AlloSure Kidney tests for Medicare reimbursement for the period from March 7, 2023 through March 31, 2023 and did not recognize revenue on these claims in the first quarter of 2023 aggregating to approximately $8.9 million, or the Impacted March Tests.
In the second quarter of 2023, we plan to submit claims for Medicare reimbursement for the Impacted March Tests, following the delivery by us of a letter to Noridian explaining, among other things, (i) our belief that the Billing Articles impose new restrictions on Medicare coverage for the CareDx tests from those contained in the existing LCDs, (ii) that we plan to submit claims for reimbursement for the Impacted March Tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (iii) that AlloSure Kidney orders with a date of service on or after March 31, 2023 for other indications outside the parameters of the Revised Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Revised Billing Article. Although we plan to submit claims for Medicare reimbursement for the Impacted March Tests, there is a risk that the claims are denied or that any reimbursement of such claims is subject to forfeiture.
We continued the Medicare reimbursement submissions for AlloMap Heart or AlloSure Heart following the issuance of the Billing Articles. In addition, we are considering informing Noridian that until Noridian adopts the Revised Billing Article, we will continue to submit AlloSure Heart tests for reimbursement only when used in conjunction with AlloMap Heart. We are also considering informing Noridian that (i) until June 30, 2023, we plan to submit claims for reimbursement for AlloMap Heart and AlloSure Heart tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (ii) AlloSure Heart and AlloMap Heart orders placed on or after June 30, 2023 for other indications outside the surveillance and for-cause parameters of the Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Billing Articles. Additionally, although we have submitted to Medicare AlloMap Heart and AlloSure Heart tests for March 2023 without confirming whether they meet the Revised Billing Article’s parameters, there is a risk that any reimbursement of such claims are subject to forfeiture.
AlloSure Kidney has received positive coverage decisions from several commercial payers, and is reimbursed by other private payers on a case-by-case basis.AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.

Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with United States Generally Accepted Accounting Principles. The preparation of these unaudited condensed consolidated 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 unaudited condensed consolidated 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.
Our significant accounting policies are described in Note 2 of the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. Some of these accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. We believe that the following critical accounting policies reflect the more significant estimates and assumptions used in the preparation of our financial statements. We believe the following critical accounting policies are affected by significant judgments and estimates used in the preparation of our unaudited condensed consolidated financial statements:
Revenue recognition;
Business combinations;
Acquired intangible assets;
Impairment of goodwill, intangible assets and other long-lived assets;
Stock-based compensation; and
Stock-based compensation.Common stock warrant liability.
There were no material changes in the matters for which we make critical accounting estimates in the preparation of our unaudited condensed consolidated financial statements during the three and nine months ended September 30, 2022March 31, 2023 as compared to those disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2021,2022, filed with the SEC on February 24, 2022.27, 2023.
Recently Issued Accounting Standards
Refer to Note 2, Summary of Significant Accounting Policies - Recent Accounting Pronouncements, to the unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for a description of recently issued accounting pronouncements, including the expected dates of adoption and estimated effects on our results of operations, financial position and cash flows.

Liquidity and Capital Resources
We have incurred significant losses and negative cash flows from operations since our inception and had an accumulated deficit of $441.5$484.9 million at September 30, 2022.March 31, 2023. As of September 30, 2022,March 31, 2023, we had cash, cash equivalents and marketable securities of $291.3$285.9 million and no debt outstanding.
The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a continued widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity.
Since March 31, 2020, and in response to the outbreak of the COVID-19 pandemic, we have increased our cash and cash equivalents. With our continuing growth, we may require additional financing in the future to fund working capital and our development of future products. Additional financing might include issuance of equity securities, including through underwritten public offerings or “at-the-market” offerings, debt offerings or financings or a combination of these financings. There can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable to us. We believe our existing cash balance and expected cash from existing operations, including cash from current license agreements and future license and collaboration agreements, or a combination of these, will be sufficient to meet our anticipated cash requirements for the next 12 months.
CMS Accelerated and Advance Payment Program for Medicare Providers
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act. Pursuant to the CARES Act, the Centers for Medicare & Medicaid Services, or CMS, expanded its Accelerated and Advance

Table of Contents
Payment Program in order to increase cash flow to providers of services and suppliers impacted by the COVID-19 pandemic. CMS was authorized to provide accelerated or advance payments during the period of the public health emergency to any Medicare provider who submitted a request to the appropriate Medicare Administrative Contractor and met the required qualifications. During April 2020, we received an advance payment from CMS of approximately $20.5 million and recorded the payment as Deferred revenue - CMS advance payment on our condensed consolidated balance sheet. During December 2020, we reassessed the Deferred revenue - CMS advance payment and repaid the entire amount in January 2021.
CARES Act Provider Relief Fund for Medicare Providers
Pursuant to the CARES Act, the U.S. Department of Health & Human Services, or HHS, distributed an initial tranche of $30.030.0 billion in funds to healthcare providers that received Medicare fee-for-service, or FFS, reimbursements in 2019. These payments to healthcare providers are not loans and will not be required to be repaid. As a condition to receiving these payments, providers must agree to certain terms and conditions and submit sufficient documentation demonstrating that the funds are being used for healthcare-related expenses or lost revenue attributable to the COVID-19 pandemic. Due to the recent enactment of legislation and absence of definitive guidance, there is a high degree of uncertainty around the CARES Act’s implementation and we continue to assess the impact on our business. Furthermore, HHS has indicated that it, along with the Office of Inspector General, will be closely monitoring and auditing providers to ensure that recipients comply with the terms and conditions of relief programs and to prevent fraud and abuse. All providers will be subject to civil and criminal penalties for any deliberate omissions, misrepresentations or falsifications of any information given to HHS. Providers will be distributed a portion of the initial $30.0 billion based on their share of total Medicare FFS reimbursements made by the U.S. in 2019. During April 2020, we received a payment of approximately $4.8 million, representing our portion of the initial tranche of funds recorded in other income (expense), net on the condensed consolidated statements of operations.
We are complying with the key terms and provisions of the CARES Act Provider Relief Fund which includes, among other things, the requirement that we maintain appropriate records and cost documentation. During the quarter ended September 30, 2021, we were notified by HHS that the Provider Relief Fund Reporting Portal was open for reporting on the use of Provider Relief Fund payments, and we completed and submitted a report indicating our use of the funds we received pursuant to the CARES Act.
January 2021 Underwritten Public Offering of Common Stock
On January 25, 2021, we sold 1,923,077 shares of our common stock through an underwritten public offering at a public offering price of $91.00 per share. The net proceeds to us from the offering were approximately $164.0 million, after deducting underwriting discounts and commissions and offering expenses.
On February 11, 2021, we sold 288,461 shares of our common stock pursuant to the full exercise of the overallotment option granted to the underwriters in connection with the offering. The net proceeds to us from the full exercise of the underwriters' overallotment option were approximately $24.7 million.

At-the-Market Equity Offering

Factors Affecting Our Performance
The Number of AlloMap Heart, AlloSure Kidney,Lung, AlloSure Lung,Kidney and AlloSure Heart Tests We Receive and Report
The growth of our testing services business is tied to the number of AlloSure Kidney, AlloSure Lung, AlloMap Heart and AlloSure Heart patient samples we receive and patient results we report. We incur costs in connection with collecting and shipping all samples and a portion of the costs when we cannot ultimately issue a report. As a result, the number of patient samples received largely correlates directly to the number of patient results reported.
AlloSure Kidney has been a covered service for Medicare beneficiaries since October 2017 through a LCD first issued by MolDX”, which was formed to identify and establish coverage and reimbursement for molecular diagnostics tests, and adopted by Noridian. The Medicare reimbursement rate for AlloSure Kidney is currently $2,841. AlloMap Heart has been a covered service for Medicare beneficiaries since January 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240. In October 2020, we received a final MolDX Medicare coverage decision for AlloSure Heart. Noridian issued a parallel coverage policy granting coverage for AlloSure Heart when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.
On March 2, 2023, MolDX issued the Billing Article. Prior to the Billing Article’s effective date, MolDX informed the affected parties, including CareDx, that enforcement of the revised billing practices outlined in the Billing Article will not be implemented until June 30, 2023. MolDX informed us that its automatic adjudication process would remain in place until June 30, 2023, though claims submitted prior to that date must comply with the applicable LCDs. On May 4, 2023, MolDX issued the Revised Billing Article. The Revised Billing Article impacts Medicare coverage for AlloSure Kidney, AlloSure Heart and AlloMap Heart and requires certain companies, including CareDx, to implement new processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, especially as it relates to when tests are covered in the for-cause and surveillance contexts.MolDX has acknowledged, however, that the Billing Article is a change as it relates to billing more than one test during a single patient encounter. Noridian has not yet adopted the new Billing Articles.
Although we believe the Billing Articles are inconsistent with the LCDs, Noridian’s and MolDX’s responses to public comments explaining the intended scope of various LCDs, and medical necessity, we determined to pause our Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 to allow us further time to evaluate the implications of the Billing Article and update our billing processes for AlloSure Kidney tests by educating clinicians and working with centers to update CareDx’s test order forms to capture the new information required under the Billing Article. Accordingly, we did not submit claims for approximately 3200 AlloSure Kidney tests for Medicare reimbursement for the period from March 7, 2023 through March 31, 2023 and did not recognize revenue on these claims in the first quarter of 2023 aggregating to approximately $8.9 million, or the Impacted March Tests.
In the second quarter of 2023, we plan to submit claims for Medicare reimbursement for the Impacted March Tests, following the delivery by us of a letter to Noridian explaining, among other things, (i) our belief that the Billing Articles impose new restrictions on Medicare coverage for the CareDx tests from those contained in the existing LCDs, (ii) that we plan to submit claims for reimbursement for the Impacted March Tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (iii) that AlloSure Kidney orders with a date of service on or after March 31, 2023 for other indications outside the parameters of the Revised Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Revised Billing Article. Although we plan to submit claims for Medicare reimbursement for the Impacted March Tests, there is a risk that the claims are denied or that any reimbursement of such claims is subject to forfeiture.
We continued the Medicare reimbursement submissions for AlloMap Heart or AlloSure Heart following the issuance of the Billing Articles. In addition, we are considering informing Noridian that until Noridian adopts the Revised Billing Article, we will continue to submit AlloSure Heart tests for reimbursement only when used in conjunction with AlloMap Heart. We are also considering informing Noridian that (i) until June 30, 2023, we plan to submit claims for reimbursement for AlloMap Heart and AlloSure Heart tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (ii) AlloSure Heart and AlloMap Heart orders placed on or after June 30, 2023 for other indications outside the surveillance and for-cause parameters of the Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Billing Articles. Additionally, although we have submitted to Medicare AlloMap Heart and AlloSure Heart tests for March 2023 without confirming whether they meet the Revised Billing Article’s parameters, there is a risk that any reimbursement of such claims are subject to forfeiture.

AlloSure Kidney has received positive coverage decisions from several commercial payers, and is reimbursed by other private payers on a case-by-case basis. AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.
Reimbursement for AlloMap Heart
AlloMap Heart test volume and the corresponding reimbursement revenue has generally increased over time since the launch of AlloMap Heart, as the ISHLT included AlloMap in guidelines, payers adopted coverage policies and no longer consider AlloMap Heart to be experimental and investigational. The rate at which our tests are covered and reimbursed has varied, and is expected to continue to vary by payer. Revenue growth depends on our ability to maintain Medicare and third party payer reimbursement, and to expand utilization by healthcare providers. See the discussion above under "The Number of AlloMap Heart, AlloSure Lung, AlloSure Kidney and AlloSure Heart Tests We Receive and Report".
The Protecting Access to Medicare Act of 2014, or PAMA, included a substantial new payment system for clinical laboratory tests under the Clinical Laboratory Fee Schedule, or CLFS. Under PAMA, laboratories that receive the majority of their Medicare revenues from payments made under the CLFS would report initially and then on a subsequent three-year basis thereafter (or annually for advanced diagnostic laboratory tests, or ADLTs), private payer payment rates and volumes for their tests. The final PAMA ruling was issued June 17, 2016 indicating that data for reporting for the new PAMA process would begin in 2017 and the new market based rates took effect on January 1, 2018. Effective January 1, 2018, Medicare reimburses us $3,240 for AlloMap Heart testing of Medicare beneficiaries, an increase from the 2017 reimbursement rate of $2,841. The CARES Act froze then-current (2020) CMS CLFS rates through 2021. Further, the CARES Act delayed the reporting cycle under PAMA to January 1 and March 31, 2022. The next data collection period will become January 1 through June 30, 2025.2024.
AlloMap Heart has also received positive coverage decisions for reimbursement from many of the largest U.S. private payers.
Reimbursement for AlloSure Kidney
On September 26, 2017, we received notice that the MolDX Program developed by Palmetto GBA had set AlloSure Kidney reimbursement at $2,841. Effective October 9, 2017, AlloSure Kidney was made available for commercial testing with Medicare coverage and reimbursement. See the discussion above under "The Number of AlloMap Heart, AlloSure Lung, AlloSure Kidney and AlloSure Heart Tests We Receive and Report". We believe the use of AlloSure Kidney, in conjunction with other clinical indicators, can help healthcare providers and their patients better manage long-term care following a kidney transplant. In particular, we believe AlloSure Kidney can improve patient care by helping healthcare providers to reduce the use of invasive biopsies and determine the appropriate dosage levels of immunosuppressants.
Reimbursement for AlloSure Heart
In October 2020, we received a final Palmetto MolDx Medicare coverage decision for AlloSure Heart. In November 2020, Noridian Healthcare Solutions, our Medicare Administrative Contractor, issued a parallel coverage policy granting coverage when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.

"The Number of AlloMap Heart, AlloSure Lung, AlloSure Kidney and AlloSure Heart Tests We Receive and Report".
Continued Growth of Product Sales
We develop, manufacture, market and sell products that increase the chance of successful transplants by facilitating a better match between a donor and a recipient of stem cells and solid organs.
Our historical product portfolio includes QTYPE and Olerup SSP.QTYPE enables speed and precision in HLA typing at a low to intermediate resolution for samples that require a fast turn-around-time and uses real-time PCR methodology. QTYPE received CE mark certification on April 10, 2018. Olerup SSP is used to type HLA alleles based on the SSP technology.
On May 4, 2018, we entered into a license and collaboration agreement with Illumina, which provides us with worldwide distribution, development and commercialization rights to Illumina's NGS product line for use in transplantation diagnostic testing. As a result, on June 1, 2018, we became the exclusive worldwide distributor of Illumina’s TruSight HLA product line. TruSight HLA is a high-resolution solution that uses NGS methodology.was discontinued in December 2021 and we have progressively converted existing customers to AlloSeq. In addition, we were granted the exclusive right to develop and commercialize other NGS product lines for use in the field of bone marrow and solid organ transplantation on diagnostic testing. These NGS products include: AlloSeq Tx, a high-resolution HLA typing solution, AlloSeq cfDNA, our surveillance solution designed to measure dd-cfDNA in blood to detect active rejection in transplant recipients, and AlloSeq HCT, a NGS solution for chimerism testing for stem cell transplant recipients.
In September 2019, we commercially launched AlloSeq cfDNA, our surveillance solution designed to measure dd-cfDNA in blood to detect active rejection in transplant recipients, which received CE mark authorization on January 20, 2020. Our ability

to increase the clinical uptake for AlloSeq cfDNA will be a result of multiple factors, including local clinical education, customer lab technical proficiency and levels of country-specific reimbursement.
Also in September 2019, we commercially launched AlloSeq Tx, the first of its kind NGS high-resolution HLA typing solution utilizing hybrid capture technology. This technology enables the most comprehensive sequencing, covering more of the HLA genes than current solutions and adding coverage of non-HLA genes that may impact transplant patient matching and management. AlloSeq Tx has a simple NGS workflow that reduces complexity and can reduce errors. AlloSeq Tx 17 received CE mark authorization on May 15, 2020.
In June 2020, we commercially launched AlloSeq HCT, a NGS solution for chimerism testing for stem cell transplant recipients. This technology has the potential to provide better sensitivity and data analysis compared to current solutions on the market. AlloSeq HCT received CE mark authorization in May 2022.
Continued Growth of Patient and Digital Sales
The growth of our patient and digital revenues is tied to the continued successful implementation of our Ottr, MedActionPlan and XynQAPI software businesses, as well as continued support and maintenance of existing MedActionPlan, Ottr Inc. and XynManagement customers. The Ottr software, TransChart, Tx Access and XynQAPI are currently implemented in multiple locations in the U.S. The Ottr software implementation and XynQAPI implementation and support teams are based in Omaha, Nebraska. In addition, patient solutions offered by TTP in Flowood, Mississippi include hospital-affiliated pharmacies located on-site at the transplant center and specialty pharmacies that provide transplant-specific care and dispensing services. With the addition of HLA Data Systems, we are now able to support HLA laboratories in managing their day-to-day workflow.
Development of Additional Services and Products
Our development pipeline includes other transplant diagnostic solutions to help clinicians and transplant centers make personalized treatment decisions throughout a transplant patient’s lifetime. We expect to invest in research and development in order to develop additional products. Our success in developing new products and services will be important in our efforts to grow our business by expanding the potential market for our services and products and diversifying our sources of revenue.
Timing of Research and Development Expenses
Our spending on research and development may vary substantially from quarter to quarter. We conduct clinical studies to validate our new products, as well as on-going clinical and outcome studies to further the published evidence to support our commercialized tests. Spending on research and development for both experiments and studies may vary significantly by quarter depending on the timing of these various expenses.
Contractual Obligations
For a discussion regarding our significant contractual obligations as of September 30, 2022March 31, 2023 and the effect those obligations are expected to have on our liquidity and cash flows in future periods, please refer to Note 9 of the condensed consolidated financial statements, and the section entitled “Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources”, respectively, included elsewhere in this Quarterly Report on Form 10-Q.
Foreign Operations
The accompanying unaudited condensed consolidated balance sheets contain certain recorded assets in foreign countries, namely Stockholm, Sweden and Fremantle, Australia. Although these countries are considered economically stable and we have experienced no notable burden from foreign exchange transactions, export duties or government regulations, unanticipated events in foreign countries could have a material adverse effect on our operations.

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.  We had cash, cash equivalents and marketable securities of $291.3$285.9 million at September 30, 2022,March 31, 2023, which consisted of bank deposits, money market funds and corporate debt securities, and we had cash and cash equivalents of $348.5$293.1 million at December 31, 2021,2022, which consisted of bank deposits and money market funds. However, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. A hypothetical 100 basis point increase or decrease in interest rates during any of the periods presented would have an approximate impact of $2.9 million on our condensed consolidated financial statements.

Foreign Currency Exchange Risk
We have operations in Sweden and Australia and sell to other countries throughout the world. As a result, we are subject to significant foreign currency risks, including transacting in foreign currencies, investment in a foreign entity, as well as assets and debts denominated in foreign currencies. Our testing services revenue is primarily denominated in U.S. dollars. Our product revenue is denominated primarily in U.S. dollars and the Euro. Our patient and digital solutions revenue is primarily denominated in U.S. dollars. Consequently, our revenue denominated in foreign currency is subject to foreign currency exchange risk. A portion of our operating expenses are incurred outside of the U.S. and are denominated in Swedish Krona, the Euro, and the Australian Dollar, which are also subject to fluctuations due to changes in foreign currency exchange rates. An unfavorable 10% change in foreign currency exchange rates for our assets and liabilities denominated in foreign currencies at September 30, 2022,March 31, 2023, would have negatively impacted our financial results for the ninethree months ended September 30, 2022March 31, 2023 by $0.2$0.4 million and our product revenue by $1.0$0.3 million. Currently, we do not have any near-term plans to enter into a formal hedging program to mitigate the effects of foreign currency volatility. We will continue to reassess our approach to managing our risk relating to fluctuations in foreign currency exchange rates.
ITEM 4.    CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures, as such terms are defined in Rules 13a-15(b)13a-15(e) and 15d-15(e) promulgated under the Exchange Act, as of September 30, 2022.March 31, 2023. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Based on such evaluation, theour Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2022,March 31, 2023, in light of the material weaknesses identified in our internal control over financial reporting described below, our disclosure controls and procedures were not effective at the reasonable assurance level and are not effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act, is (i) recorded, processed, summarized and reported as and when required and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely discussion regarding required disclosure.
Previously Reported Material Weaknesses
As disclosed in Item 9A, “Controls and Procedures” within our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on February 27, 2023, the following material weaknesses were identified as of December 31, 2022:
General Information Technology Controls. We did not design and maintain effective general information technology controls (“GITCs”), for information systems and applications that are relevant to the preparation of the consolidated financial statements. Specifically, we did not design and maintain: (i) sufficient user access controls to ensure appropriate segregation of duties, logical access controls to prevent unauthorized user access and adequately restrict user and privileged access to financial applications, programs and data to appropriate Company personnel; (ii) program change management controls to ensure that information technology (“IT”), program and data changes affecting financial IT applications and underlying accounting records are identified, tested, authorized and implemented appropriately with appropriate segregation of duties; and (iii) Computer and Network operations controls to ensure that batch and interface jobs are monitored and privileges are appropriately granted, authorized and monitored. As a result, business process controls (automated and manual) that are dependent on the ineffective GITCs, or that rely on data produced from systems impacted by the ineffective GITCs, are also deemed ineffective, which affects substantially all financial statement account balances and disclosures.
49

Table of Contents
Purchase Order Approval Workflow. We did not design and maintain effective process-level control activities related to procurement to ensure appropriate approval of purchase orders, which could affect the amount and classification of costs capitalized or expensed.
COSO Framework. We did not fully maintain components of the COSO framework, including elements of the control environment, information and communication, and control activities and monitoring activities components, relating to: (i) sufficiency of competent personnel to perform internal control activities and support the achievement of our internal control objectives; (ii) enforcing accountability of personnel for the performance of their internal control responsibilities across the organization in the pursuit of objectives; (iii) designing and maintaining general control activities over technology to support the achievement of our internal control objectives; (iv) performing control activities in accordance with established policies in a timely manner; and (v) performing sufficient reviews of information to assess its relevance, accuracy, and completeness in supporting the internal control components. As such, our management concluded that we did not have an adequate process in place to complete our assessment of the design and operating effectiveness of internal control over financial reporting in a timely manner.
After giving full consideration to these material weaknesses, and the additional analyses and other procedures we performed to ensure that our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, our management has concluded that our condensed consolidated financial statements present fairly, in all material respects, our financial position, results of operations and cash flows for the periods disclosed in conformity with U.S. GAAP.
Management’s Plan to Remediate the Material Weaknesses
Our management has been engaged in developing and implementing remediation plans to address the material weaknesses described above. These remediation efforts are ongoing and are expected to include the following:
Enhancing the design and control procedures of the GITCs to ensure that the control activities related to GITCs are functioning appropriately;
Improving the control environment in relation to personnel training and accountability of Sarbanes-Oxley Act of 2002 ("SOX") control activities;
Hiring additional personnel in the IT and Finance and Accounting departments with an appropriate level of knowledge and experience to effectively execute our processes and procedures; and
Expanding controls and/or applying appropriate procedures to address the design and operation of internal controls related to the procure-to-pay process.
In 2023 to date, we have hired three additional full time and contractors resources in our IT and Finance and Accounting departments to support our remediation efforts. We expect, and are planning, to continue adding incremental staffing in these departments throughout the year. We are in the process of developing and delivering SOX compliance training to control owners and are also actively working on and updating the design of our controls and controls procedures to ensure we address the root causes of the material weaknesses. We have also enhanced our communication by frequently holding meetings with key management personnel and members of the Audit Committee to discuss the SOX program. In regards to the procure-to-pay process, we are implementing a new automated control for the purchase order approval workflow and a new accounts payable system. In addition, we are investing in and implementing other systems that will assist us in monitoring the timely execution of controls, and we expect to continue to implement these throughout the remaining part of the year.
We are committed to continuing to implement a strong system of controls and believe that our ongoing remediation efforts particularly in the improvement of our control environment will result in significant improvements to our system of controls and that we believe will remediate the material weaknesses. However, material weaknesses are not considered remediated until the new controls have been operational for a period of time, are tested, and management concludes that these controls are operating effectively. This remediation process will require resources and time to implement. We will continue to monitor the effectiveness of these remediation measures, and we will make any changes to the design of our remediation plans and take such other actions that we deem appropriate given the circumstances.
Changes in Internal ControlsControl over Financial Reporting

ITEM 1A. RISK FACTORS

Our Annual Report on Form 10-K for the year ended December 31, 2021,2022, filed with the Securities and Exchange Commission or the SEC, on February 24, 2022,27, 2023, or the Form 10-K, Part I –Item 1A, Risk Factors, describes important risk factors that could cause our business, financial condition, results of operations and growth prospects to differ materially from those indicated or suggested by forward-looking statements made in this Quarterly Report on Form 10-Q or presented elsewhere by management from time to time.  There have been no material changes in the risk factors that appear in Part I - Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2021,2022, filed with the SEC on February 24, 2022,27, 2023, other than those listed below. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business.
Risks Related to Our Business
We have a history of losses, and we expect to incur net losses for the next several years.
We have incurred substantial net losses since our inception, and we may continue to incur additional losses for the next several years. For the quarter ended September 30, 2022,March 31, 2023, our net loss was $16.9$23.7 million. As of September 30, 2022,March 31, 2023, we had an accumulated deficit of $441.5$484.9 million. We expect to continue to incur significant operating expenses and anticipate that our expenses will increase due to costs relating to, among other things:
researching, developing, validating and commercializing potential new testing services, products and patient and digital solutions, including additional expenses in connection with our continuing development and commercialization of KidneyCare, HeartCare, AlloSeq, AiTraC and other future solutions;
developing, presenting and publishing additional clinical and economic utility data intended to increase payer coverage and clinician adoption of our current and future solutions;
expansion of our operating capabilities;
maintenance, expansion and protection of our intellectual property portfolio and trade secrets;
the process of fully integrating acquired companies and operations and the associated potential disruptions to our business;
future clinical trials;
expansion of the size and geographic reach of our sales force and our marketing capabilities to commercialize our existing and future solutions;
employment of additional clinical, quality control, scientific, customer service, laboratory, billing and reimbursement and management personnel;
compliance with existing and changing laws, regulations and standards, including those relating to corporate governance and public disclosure and regulations implemented by the Securities and Exchange Commission, or the SEC, and The Nasdaq Stock Market LLC;  
employment of operational, financial, accounting and information systems personnel, consistent with expanding our operations and our status as a public company; and
failure to achieve expected operating results may cause a future impairment of goodwill or other assets.
Even if we achieve significant revenues, we may not become profitable, and even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain consistently profitable could adversely affect the market price of our common stock and could significantly impair our ability to raise capital, expand our business or continue to pursue our growth strategy or even continue to operate. For a detailed discussion of our financial condition and results of operations, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We may require additional financing.
As of September 30, 2022, we had cash, cash equivalents and marketable securities of $291.3 million and an accumulated deficit of $441.5 million. We may require additional financing in the future to fund working capital, pay our obligations as they come due and fund our acquisitions of complementary businesses and assets. Additional financing might include issuance of equity securities, debt, cash from collaboration agreements, or a combination of these. However, there can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable to us.
We receive a substantial portion of our revenues from Medicare, and the loss of, or a significant reduction in, reimbursement from Medicare would severely and adversely affect our financial performance.
For the quarter ended September 30, 2022,March 31, 2023, revenue from Medicare for AlloMap Heart, AlloSure Kidney and AlloSure Heart represented 64%53% of testing services revenue. However, we may not be able to maintain or increase our tests reimbursed by Medicare for a variety of reasons, including changes in reimbursement practices, general policy shifts, or reductions in reimbursement amounts. We cannot predict whether Medicare reimbursements will continue at the same payment amount or with the same breadth of coverage in the future, if at all.
The Protecting Access to Medicare Act of 2014, or PAMA, included a substantial new payment system for clinical laboratory tests under the Clinical Laboratory Fee Schedule, or CLFS. Under PAMA, laboratories that receive the majority of their Medicare revenues from payments made under the CLFS report initially and then on a subsequent three-year basis thereafter (or annually for advanced diagnostic laboratory tests, or ADLTs), private payer payment rates and volumes for their tests. The final PAMA ruling was issued on June 17, 2016 and the new market based rates took effect on January 1, 2018. The Centers for Medicare & Medicaid Services, or CMS, uses the rates and volumes reported by laboratories to develop Medicare payment rates for the tests equal to the volume-weighted median of the private payer payment rates for the tests. Under PAMA, the reimbursement rate for AlloMap Heart is currently $3,240 for Medicare beneficiaries.
On September 26, 2017, we announced that the Molecular Diagnostic Services, or MolDX, Program developed by Palmetto GBA, or Palmetto, has set AlloSure Kidney reimbursement at $2,841. AlloSure Kidney began to be reimbursed for kidney transplants covered by Medicare across the United States on October 9, 2017, the effective date of the Palmetto local coverage determination, or LCD.
AlloSure Kidney has been a covered service for Medicare beneficiaries since October 2017 through an LCD first issued by Palmetto MolDX, or MolDX, which was formed to identify and establish coverage and reimbursement for molecular diagnostics tests, and adopted by Noridian Healthcare Solutions, the Company’s Medicare Administrative Contractor, or Noridian. The Medicare reimbursement rate for AlloSure Kidney is currently $2,841. AlloMap Heart has been a covered service for Medicare beneficiaries since January 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240. In October 2020, AlloSure Heartwe received a final Palmetto MolDxMolDX Medicare coverage decision for AlloSure Heart. In November 2020, Noridian Healthcare Solutions, our Medicare Administrative contractor, issued a parallel coverage policy granting coverage for AlloSure Heart when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.
On March 2, 2023, MolDX issued a new billing article, with an effective date of March 31, 2023, related to the LCD entitled Molecular Testing for Solid Organ Allograft Rejection, or the Billing Article. Prior to the Billing Article’s effective date, MolDX informed the affected parties, including CareDx, that enforcement of the revised billing practices outlined in the Billing Article will not be implemented until June 30, 2023. MolDX informed us that its automatic adjudication process would remain in place until June 30, 2023, though claims submitted prior to that date must comply with the applicable LCDs. On May 4, 2023, MolDX issued a revised new billing article with an effective date of March 31, 2023, or the Revised Billing Article, and together with the Billing Article, the Billing Articles. The Revised Billing Article impacts Medicare coverage for AlloSure Kidney, AlloSure Heart and AlloMap Heart and requires certain companies, including CareDx, to implement new processes to address the requirements related to Medicare claim submissions. MolDX has stated that it views the Billing Article as clarifying existing coverage, especially as it relates to when tests are covered in the for-cause and surveillance contexts.MolDX has acknowledged, however, that the Billing Article is a change as it relates to billing more than one test during a single patient encounter. Noridian has not yet adopted the new Billing Articles.
Although we believe the Billing Articles are inconsistent with the LCDs, Noridian’s and MolDX’s responses to public comments explaining the intended scope of various LCDs, and medical necessity, we determined to pause its Medicare reimbursement submissions for AlloSure Kidney commencing on March 7, 2023 to allow us further time to evaluate the implications of the Billing Article and update its billing processes for AlloSure Kidney tests by educating clinicians and working with centers to update our test order forms to capture the new information required under the Billing Article. Accordingly, we did not submit claims for approximately 3200 AlloSure Kidney tests for Medicare reimbursement for the period from March 7, 2023 through March 31, 2023 and did not recognize revenue on these claims in the first quarter of 2023 aggregating to approximately $8.9 million, or the Impacted March Tests.
In the second quarter of 2023, we plan to submit claims for Medicare reimbursement for the Impacted March Tests, following the delivery by our of a letter to Noridian explaining, among other things, (i) we believe that the Billing Articles impose new restrictions on Medicare coverage for our tests from those contained in the existing LCDs, (ii) that we plan to submit claims for reimbursement for the Impacted March Tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (iii) that AlloSure Kidney orders with a date of service on or after March 31, 2023 for other indications outside the parameters of the Revised Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is

Table of Contents
intended to identify those tests as falling outside the parameters of the Revised Billing Article. Although we plan to submit claims for Medicare reimbursement for the Impacted March Tests, there is a risk that the claims are denied or that any reimbursement of such claims is subject to forfeiture.
We continued the Medicare reimbursement submissions for AlloMap Heart or AlloSure Heart following the issuance of the Billing Articles. In addition, we are considering informing Noridian that until Noridian adopts the Revised Billing Article, we will continue to submit AlloSure Heart tests for reimbursement only when used in conjunction with AlloMap Heart. We are also considering informing Noridian that (i) until June 30, 2023, we plan to submit claims for reimbursement for AlloMap Heart and AlloSure Heart tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles, and (ii) AlloSure Heart and AlloMap Heart orders placed on or after June 30, 2023 for other indications outside the surveillance and for-cause parameters of the Billing Article, or where the reason for testing is not specified by the ordering physician, will either be held pending the receipt of additional information regarding medical necessity or submitted with a test description that is intended to identify those tests as falling outside the parameters of the Billing Articles. There is a risk that claims submitted for reimbursement through June 30, 2023 for AlloMap Heart and AlloSure Heart tests for which we have not obtained additional information from the ordering physicians to be able to specifically determine whether these tests meet the new coverage restrictions contained in the Billing Articles subject to forfeiture.
If an AlloMap Heart, AlloSure Kidney or AlloSure Heart reimbursement rate that is significantly lower than the current rate is set by CMS or MolDx in the future, it could cause us to discontinue AlloMap Heart, AlloSure Kidney or AlloSure Heart testing for Medicare patients because providing tests at a substantially lowered reimbursement rate may not be economically viable. In addition, our revenues for AlloSure Kidney in 2023 are expected to be materially lower than in prior periods as a result of lower overall testing volumes in 2023 due to the impact of the Billing Articles. Given the significant portion of payments represented by Medicare, our remaining test revenue may be insufficient to sustain our operations.
If future reimbursement price levels are less than the current price, our revenues and our ability to achieve profitability could be impaired, and the market price of our common stock could decline. We may also not be able to maintain or increase the portion of our tests reimbursed by Medicare for a variety of other reasons, including changes in reimbursement practices and general policy shifts.shifts, including the Billing Articles.
On a five-year rotational basis, Medicare requests bids for its regional Medicare Administrative Contractors, or MAC, services. The MAC for California is currently Noridian Healthcare Solutions. Our current Medicare coverage through Noridian provides for reimbursement for tests performed for qualifying Medicare patients throughout the U.S. so long as the tests are performed in our California laboratory. We cannot predict whether Noridian or any future MAC will continue to provide reimbursement for AlloMap Heart, AlloSure Kidney or AlloSure Heart at the same payment amount or with the same breadth of coverage in the future, if at all. Additional changes in the MAC processing Medicare claims for AlloSure Kidney, AlloMap Heart or AlloSure Heart could impact the coverage or payment amount for our tests and our ability to obtain Medicare coverage for any products we may launch in the future.
Any decision by CMS or its local contractors to reduce or deny coverage for our tests, including as a result of the Billing Articles or otherwise, would have a significant adverse effect on our revenue and results of operations and ability to operate and raise capital. Any such decision could also cause affected clinicians treating Medicare covered patients to reduce or discontinue the use of our tests.

Our financial results currently are largely dependent on sales of AlloSure Kidney, AlloMap Heart and AlloSure Lung tests and products, and we will need to generate sufficient revenues from these and other solutions and tests we develop to grow our business.

TableWe expect that sales of Contents
testing services and products will account for a substantial portion of our revenue for at least the next two years. If we are unable to increase sales of our testing services or products or successfully develop and commercialize other solutions, tests or enhancements, or if we do not recommence our Medicare reimbursement submissions for AlloSure Kidney in the near term or at the same levels in place prior to the Billing Articles, our revenues and ability to achieve profitability would be impaired, and the market price of our common stock could decline.
Health insurers and other third-party payers may decide to revoke coverage of our existing test, decide not to cover our future solutions or may provide inadequate reimbursement, which could jeopardize our commercial prospects.
Successful commercialization of AlloSure Kidney, AlloSure Lung, AlloMap Heart and AlloSure Heart depends, in large part, on the availability of coverage and adequate reimbursement from government and private payers. Favorable third-party payer coverage and reimbursement are essential to meeting our immediate objectives and long-term commercial goals.
For new diagnostic testing services, each private and government payer decides whether to cover the test, the amount it will reimburse for a covered test and the specific conditions for reimbursement. Clinicians and recipients may be likely not to order
53

Table of Contents
a diagnostic test unless third-party payers pay a substantial portion of the test price. Therefore, coverage determinations and reimbursement levels and conditions are critical to the commercial success of a diagnostic testing service, and if we are not able to secure positive coverage determinations and reimbursement levels, our business will be materially adversely affected.
Coverage and reimbursement by a commercial payer may depend on a number of factors, including a payer’s determination that our current and future testing services are:

not experimental or investigational;
medically necessary or redundant;
lead to improved patient outcomes;
appropriate for the specific recipient;
cost-saving or cost-effective; and
supported by peer-reviewed publications.

Third-party payers have in the past disallowed, and may in the future disallow, in whole or in part, requests for reimbursement based on determinations that the member is not eligible for coverage, certain amounts are not reimbursable under plan coverage or were for services provided that were not medically necessary or were redundant or not coupled with other specified tests or services or additional supporting documentation is necessary. Retroactive adjustments may change amounts realized from third-party payers. We are also subject to claims reviews and/or audits by such payers, including governmental audits of our Medicare claims, and have in the past been required to repay these payers in certain circumstances where a preliminary finding was made that we were incorrectly reimbursed. We may also in the future be required to repay these payers if a finding is made that we were incorrectly reimbursed.
In addition, several payers and other entities conduct technology assessments of new medical tests and devices and provide and/or sell the results of their assessments to other parties. These assessments may be used by third-party payers and healthcare providers as grounds to deny coverage for or refuse to use a test or procedure. We have received a negative technology assessment from at least one of these entities and could receive more.
If third-party payers decide not to cover our diagnostic testing services or if they offer inadequate payment amounts, our ability to generate revenue from AlloSure Kidney, AlloMap Heart, AlloSure Heart and future solutions could be limited. Payment for diagnostic tests furnished to Medicare beneficiaries is typically made based on a fee schedule set by CMS. In recent years, payments under these fee schedules have decreased and may decrease further.
Any third-party payer may stop or lower payment at any time, which could substantially reduce our revenue. See the risk factor above titled “We“We receive a substantial portion of our revenues from Medicare, and the loss of, or a significant reduction in, reimbursement from Medicare would severely and adversely affect our financial performance”.
Since each payer makes its own decision as to whether to establish a policy to reimburse for a test, seeking payer coverage and other approvals is a time-consuming and costly process. We cannot be certain that adequate coverage and reimbursement for AlloSure Kidney, AlloSure Lung, AlloMap Heart, AlloSure Heart, or future solutions will be provided in the future by any third-party payer.
Reimbursement for AlloSure Kidney, AlloMap Heart and AlloSure Heart comes primarily from Medicare and private third party payers such as insurance companies and managed care organizations. The reimbursement process can take six months or more to complete depending on the payer. AlloSure Kidney has been a covered service for Medicare beneficiaries since October 2017 through a LCD first issued by MolDX, which was formed to identify and establish coverage and reimbursement for molecular diagnostics tests, and adopted by Noridian. The Medicare reimbursement rate for AlloSure Kidney is currently $2,841. AlloMap Heart has been a covered service for Medicare beneficiaries since January 2006. The Medicare reimbursement rate for AlloMap Heart is currently $3,240. In October 2020, we received a final MolDX Medicare coverage decision for AlloSure Heart. Noridian issued a parallel coverage policy granting coverage for AlloSure Heart when used in conjunction with AlloMap Heart, which became effective in December 2020. The Medicare reimbursement rate for AlloSure Heart is currently $2,753.See the discussion regarding the Billing Articles under the risk factor above titled “We receive a substantial portion of our revenues from Medicare, and the loss of, or a significant reduction in, reimbursement from Medicare would severely and adversely affect our financial performance”.
Coverage policies approving AlloMap Heart have been adopted by many of the largest private payers. Many of the payers with positive coverage policies have also entered into contracts with us to formalize pricing and payment terms. We continue to work with third-party payers to expand and seek such coverage and to appeal denial decisions based on existing and ongoing studies, peer reviewed publications, support from physician and patient groups and the growing number of AlloMap Heart tests that have been reimbursed by public and private payers. There are no assurances that the current policies will not be modified in the future. If our test is considered on a policy-wide level by major third-party payers, whether at our request or on their own initiative, and our test is determined to be ineligible for coverage and reimbursement by such payers, if we do not submit for

Medicare reimbursement for AlloSure Kidney for certain prior or future periods or if the Billing Articles limit Medicare reimbursement for AlloSure Heart or AlloMap Heart commencing on June 30, 2023, our collection efforts and potential for revenue growth could be adversely impacted.

Our Medicare Part B coverage for AlloSure Kidney and AlloMap Heart is included in a formal local coverage decision for molecular diagnostics. However, any change in this coverage decision or other future adverse coverage decisions by the CMS, including with respect to coding or as a result of the Billing Articles, could substantially reduce our revenue.
Medicare reimbursements currently comprise a significant portion of our revenue. Our current Medicare Part B reimbursement was not set pursuant to a national coverage determination by CMS. Although we believe that coverage is available under Medicare Part B even without such a determination, we currently lack the national coverage certainty afforded by a formal coverage determination by CMS. This means that Medicare contractors, including our California Medicare contractor, currently may continue to develop their own coverage and reimbursement policies with respect to our technology.
Until 2016, AlloMap Heart was billed using an unlisted Current Procedural Terminology, or CPT, code, but in 2016 a new CPT Category 1 Multianalyte Assays with Algorithmic Analyses, or MAAA, code was added that specifically describes the test. Further, pursuant to MolDX billing requirements, the AlloMap Heart test also has been assigned a McKesson Diagnostics Z code™, which is included on all Medicare claims.
If in the future CMS makes a determination not to pay for this code, or for any MAAA codes, this could be harmful to our business, and could have negative spillover implications that prevent or limit coverage by other third-party payers that might mirror aspects of Medicare payment criteria.
Since the launch of AlloSure Kidney in October 2016, and at the instruction of the MolDX Program of Palmetto, the test has been billed utilizing an unlisted CPT code. If in the future CMS makes a determination to no longer provide coverage for services billed with an unlisted CPT code, our ability to bill and obtain reimbursement from public and private payers could be negatively impacted. In addition, the Billing Article indicates that we will need to obtain additional “Z” codes for AlloSure Kidney in order to submit for future Medicare reimbursement. In addition, there can be no assurance that any of our tests or other offerings currently being promoted or on the market or being leveraged by clinicians or patients without FDA clearance or approval will continue to be allowed without such clearance or approval.
We are and could become subject to legal proceedings that could be time consuming, result in costly litigation and settlements/judgments, require significant amounts of management attention and result in the diversion of significant operational resources, which could adversely affect our business, financial condition and results of operations.
We have in the past been, and from time to time in the future may become, involved in lawsuits, claims and proceedings incident to the ordinary course of, or otherwise in connection with, our business. For example, in response to our false advertising suit filed against Natera Inc., or Natera, on April 10, 2019, Natera filed a counterclaim against us on February 18, 2020 in the U.S. District Court for the District of Delaware, or the Court, alleging we made false and misleading claims about the performance capabilities of AlloSure. The suit seeks injunctive relief and unspecified monetary relief. On September 30, 2020, Natera requested leave of the Court to amend its counterclaims to include additional allegations regarding purportedly false claims we made with respect to AlloSure, and the Court granted Natera’s request. The trial date commenced on March 7, 2022 and concluded on March 14, 2022, with the jury awarding us $44.9 million in damages, comprised of $21.2 million in compensatory damages and $23.7 million in punitive damages. Post-trialAs of the date of this report, the post-trial motion practice remains pending. We will not record the award until cash is received or the matter is otherwise resolved.
On July 19, 2022, the United States Court of Appeals for the Federal Circuit court of appeals affirmed the district court’sCourt's judgment dismissing our patent infringement suit against Natera.
In addition, in response to our patent infringement suit filed against Natera on March 26, 2019, Natera filed suit against us on January 13, 2020 in the Court alleging, among other things, that AlloSure infringes Natera’s U.S. Patent 10,526,658. This case was consolidated with our patent infringement suit on February 4, 2020. On March 25, 2020, Natera filed an amendment to the suit alleging, among other things, that AlloSure also infringes Natera’s U.S. Patent 10,597,724. The suit seeks a judgment that we have infringed Natera’s patents, an order preliminarily and permanently enjoining us from any further infringement of such patents and unspecified damages. On May 13, 2022, Natera filed two new complaints alleging that AlloSure infringes Natera’s U.S. Patents 10,655,180 and 11,111,544. These two cases were consolidated with the patent infringement case on June 15, 2022. On May 17, 2022, Natera agreed to dismiss the case alleging infringement of Natera’s U.S. Patent 10,526,658. On July 6, 2022, we moved to dismiss the rest of Natera’s claims. On September 6, 2022, we withdrew the motion to dismiss. Discovery is ongoing. We intend to defend both of these matters vigorously, and believe that we have good and substantial defenses to the claims alleged in the suits, but there is no guarantee that we will prevail.
Furthermore, on May 23, 2022, Plumbers & Pipefitters Local Union #295 Pension Fund filed a federal securities class action in the U.S. District Court for the Northern District of California against us, Reginald Seeto, our President, Chief Executive Officer

The action alleges that we and the individual defendants made materially false and/or misleading statements and/or omissions and that such statements violated Section 10(b) of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”),or the Exchange Act, and Rule 10b-5 promulgated thereunder. The action also alleges that the individual defendants are liable pursuant to Section 20(a) of the Exchange Act as controlling persons of our Company. The suit seeks to recover damages caused by the alleged violations of

federal securities laws, along with the plaintiffs’ costs incurred in the lawsuit, including their reasonable attorneys’ and experts’ witness fees and other costs. We intend to defend ourselves vigorously, and believe that we have good and substantial defenses to the claims alleged in the suit, but there is no guarantee that we will prevail.
On August 25, 2022, the court appointed an investor group led by the Oklahoma Police Pension and Retirement System as lead plaintiffs and appointed Saxena White P.A. and Robbins Geller Rudman & Dowd LLP as lead counsel. On September 12, 2022, the court entered a schedule pursuant to which Plaintiffs’counsels. Plaintiffs filed an amended complaint is due on November 11, 2022; Defendants’ motion28, 2022. On January 27, 2023, defendants moved to dismiss all claims and to strike certain allegations in the amended complaint. A hearing on these motions is due on January 10, 2023; Plaintiffs’ opposition to the motion to dismiss is due on February 24, 2023; and Defendants’ reply is due on March 26,scheduled for May 16, 2023. We intend to defend itselfourselves vigorously, and believes that we have good and substantial defenses to the claims alleged in the suit, but there is no guarantee that we will prevail.
Additionally, on September 21, 2022, Jeffrey Edelman brought a stockholder derivative action complaint in the U.S. District Court for the Northern District of California, or the Edelman Derivative Action, against us as nominal defendant and Reginald Seeto, our President, Chief Executive Officer and member of our Board of Directors, Ankur Dhingra, our former Chief Financial Officer, Peter Maag, our former President, former Chief Executive Officer, former Chairman of the Board and current member of our Board of Directors, and the other members of our Board of Directors. The plaintiff alleges that the individual defendants breached their fiduciary duties as directors and/or officers of our Company and engaged in insider trading, waste of corporate assets, unjust enrichment and violations of Sections 14(a) and 20(a) of the Exchange Act. The action alleges that the individual defendants are liable pursuant to Section 20(a) of the Exchange Act as controlling persons of our Company. The suit seeks a declaration that the individual defendants breached their fiduciary duties to us, violated Sections 14(a) and 20(a) of the Exchange Act and were unjustly enriched, and also seeks to recover damages sustained by us as a result of the alleged violations, along with the plaintiff’s costs incurred in the lawsuit, including reasonable attorneys’ and experts’ fees, costs and expenses.
In addition, on February 7, 2023, Jaysen Stevenson brought a stockholder derivative action complaint in the U.S. District Court for the Northern District of California, or the Stevenson Derivative Action, against us as nominal defendant and Reginald Seeto, Ankur Dhingra, Peter Maag and other current and former members of our Board of Directors. The claims and allegations in the Stevenson Derivative Action are substantially similar to those in the Edelman Derivative Action. The plaintiff alleges that the individual defendants breached their fiduciary duties as our directors and/or officers and engaged in insider trading, waste of corporate assets, unjust enrichment and violations of Sections 14(a) and 20(a) of the Exchange Act. The suit seeks declaratory relief and to recover alleged damages sustained by us as a result of the alleged violations, along with the plaintiff’s costs incurred in the lawsuit, including reasonable attorneys’ and experts’ fees, costs and expenses.
We intend to defend ourselves vigorously, and we believe that we have good and substantial defenses to the claims alleged in the action,Edelman Derivative Action and the Stevenson Derivative Action, but there is no guarantee that we will prevail.
Litigation is inherently unpredictable. It is possible that an adverse result in one or more of these possible future events could have a material adverse effect on us including increased expenses to defend, settle or resolve such litigation.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our testing services for the U.S.common stock could decline substantially. Furthermore, any quarterly fluctuations in our laboratory locatedoperating results may, in Brisbane, California. We do not have redundant laboratory facilities. Brisbane, California is situated on or near earthquake fault lines. Our facility andturn, cause the equipment we use to perform testing services would be costly to replace and could require substantial lead time to repair or replace if damaged or destroyed. Our facilities may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, power outages, wildfires, flooding, hurricanes, droughts and other extreme weather events and changing weather patterns, which are increasing in frequency due to the impacts of climate change and may render it difficult or impossible for us to perform our tests for some period of time. The inability to perform our tests may result in the loss of customers or harm our reputation, and we may be unable to regain those customers in the future. Although we possess insurance for damage to our property and the disruptionprice of our business, we dostock to fluctuate substantially. We believe that quarterly comparisons of our financial results are not have earthquake insurancenecessarily meaningful and thus coverage mayshould not be sufficient to cover allrelied upon as an indication of our potential losses andfuture performance.
Transplant centers may not continue to be available to us on acceptable terms, if at all.
In order to establish a redundant laboratory facility, we would have to spend considerable time and money securing adequate space, constructing the facility, recruiting and training employees and establishing the additional operational and administrative infrastructure necessary to support a second facility. Additionally, any new clinical laboratory facility opened by us in the U.S. would be required to be certified under the Clinical Laboratory Improvement Amendments of 1988, or CLIA, a federal law that regulates clinical laboratories that perform testing on specimens derived from humans for the purpose of providing information for the diagnosis, prevention or treatment of disease. We would also be required to secure and maintain state licenses required by several states, including California, Florida, Maryland, New York, Rhode Island and Pennsylvania, which can take a significant amount of time and result in delays in our ability to begin operations at that facility.
If we failed to secure any such licenses, we would not be able to process samples from recipients in such states. We also expect that it would be difficult, time-consuming and costly to train, equip and use a third-party to perform tests on our behalf. We could only use another facility with the established state licensures and CLIA certification necessary to perform AlloSure Kidney, AlloSure Lung, AlloMap Heart, AlloSure Heart, or future solutions following validation and other required procedures. We cannot be certain that we would be able to find another CLIA-certified facility willing or able to adopt AlloSure Kidney, AlloSure Lung, AlloMap Heart, AlloSure Heart, or futureour other solutions due to historical practices or abledue to complymore favorable reimbursement policies associated with other means of monitoring transplants.
Due to the required qualityhistorically limited monitoring options and regulatory standards,the well-established coverage and reimbursement for biopsies, clinicians are accustomed to monitoring for acute rejection in kidney and heart transplant recipients by utilizing biopsies. Many clinicians use AlloSure Kidney, AlloSure Lung, AlloMap Heart and AlloSure Heart in parallel with biopsies rather than as an alternative to biopsies. While we do not market AlloSure Kidney, AlloSure Lung, AlloMap Heart or that this laboratoryAlloSure Heart as biopsy alternatives, per se, if treatment center administrators view our test as an alternative to a biopsy but believe they would be willing or able to performderive more revenue from the tests for us on commercially reasonable terms.
Since the onsetperformance of the COVID-19 pandemic, federal, state and local governments have imposed various quarantines, shelter-in-place and similar government orders, including several orders that previously impacted operations in San Mateo County, where our laboratory and headquarters are located. These orders and othersbiopsies, such administrators may be reinstated depending uponmotivated to reduce or avoid the COVID-19use of our test. While biopsies are less common for monitoring kidney transplant patients, there are transplant centers that manage patients with protocol biopsies, which could impact AlloSure Kidney revenue. We cannot provide assurance that our efforts will increase the use of our test by new or existing customers. Our failure to increase the frequency of use of our test by new and existing customers would adversely affect our growth and revenues.
Our past revenue growth rates may not be indicative of future growth, and we may not grow at all, and revenue may decline.
From 2021 to 2022, our revenue grew from $296.4 million to $321.8 million, which represents annual growth of 9%. In the future, our revenue may not grow at all and it may decline. We believe that our future revenue will depend on, among other factors:
the continued usage and acceptance of our current and future solutions;
demand for our testing services, products and patient and digital solutions;
the introduction and acceptance of new or enhanced products or services by us or by competitors;
our ability to maintain reimbursement for AlloSure Kidney, AlloSure Lung, AlloMap Heart and AlloSure Heart and secure reimbursement for our future solutions;

Investors’ expectations of our performance relating to environmental, social and governance factors may impose additional costs and expose us to new risks.
There is an increasing focus from certain investors, employees, regulators and other stakeholders concerning corporate responsibility, specifically related to environmental, social and governance, or ESG, factors. Some investors and investor advocacy groups may use these factors to guide investment strategies and, in some cases, investors may choose not to investsuccessful in our company if they believe our policies relatingefforts to corporate responsibility are inadequate. Third-party providersmanage any of corporate responsibility ratingsthe foregoing, and reports on companies have increasedany failure to meet growing investor demand for measurement of corporate responsibility performance,be successful in these efforts could materially and a variety of organizations currently measure the performance of companies on such ESG topics, and the results of these assessments are widely publicized. Investors, particularly institutional investors, use these ratings to benchmark companies against their peers and if we are perceived as lagging with respect to ESG initiatives, these investors may engage with us to improve ESG disclosures or performance and may also make voting decisions, or take other actions, to hold us and our board of directors accountable. In addition, the criteria by which our corporate responsibility practices are assessed may change, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new criteria. If we elect not to or are unable to satisfy such new criteria, investors may conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational damage in the event that our corporate responsibility procedures or standards do not meet the standards set by various constituencies.
We may face reputational damage in the event our corporate responsibility initiatives or objectives do not meet the standards set by our investors, stockholders, lawmakers, listing exchanges or other constituencies, or if we are unable to achieve an acceptable ESG or sustainability rating from third-party rating services. A low ESG or sustainability rating by a third-party rating service could also result in the exclusion of our common stock from consideration by certain investors who may elect to invest with our competition instead. Ongoing focus on corporate responsibility matters by investors and other parties as described above may impose additional costs or expose us to new risks. Any failure or perceived failure by us in this regard could have a material adverse effect on our reputation and on our business, share price, financial condition or results of operations, including the sustainability of our business over time. In addition, the SEC has announced proposed rules that, among other matters, will establish a framework for reporting of climate-related risks. To the extent the proposed rules impose additional reporting obligations, we could face increased costs. Separately, the SEC has also announced that it is scrutinizing existing climate-change related disclosures in public filings, increasing the potential for enforcement if the SEC were to allege our existing climate disclosures are misleading or deficient.

We rely heavily on providersbe indicative of transport services for reliable and secure point-to-point transport of recipient samples to our laboratory and enhanced tracking of these recipient samples. Should a carrier encounter delivery performance issues such as loss, damage or destruction of a sample, it may be difficult to replace our patient samples in a timely manner and such occurrences may damage our reputation and lead to decreased demand for our services and increased cost and expense to our business. In addition, any significant increase in shipping rates could adversely affect our operating margins and results of operations. Similarly, strikes, severe weather, natural disasters or other service interruptions, including those related or attributable to the COVID-19 pandemic, or related to the ongoing conflict between Ukraine and Russia and the global impact of restrictions and sanctions imposed on Russia, affecting delivery services we use would adversely affect our ability to receive and process recipient samples on a timely basis.future growth.
If we are unable to raise additional capital on acceptable terms in the future, it may limit our ability to develop and commercialize new diagnostic solutions and technologies, and we may have to curtail or cease operations.
As of March 31, 2023, we had cash, cash equivalents and marketable securities of $285.9 million and an accumulated deficit of $484.9 million. We expect capital outlays and operating expenditures to increase over the next several years as we expand our infrastructure, commercial operations and research and development activities. Specifically, we may need to raise additional capital to, among other things:
develop other solutions for clinical surveillance in transplantation;
increase our selling and marketing efforts to drive market adoption and address competitive developments;
expand our clinical laboratory operations;
fund our clinical validation study activities;

expand our research and development activities;
sustain or achieve broader commercialization of AlloSure Kidney, AlloSure Lung, KidneyCare, AlloMap Heart, AlloSure Heart, HeartCare, our products and patient and digital solutions or enhancements to those tests, products and patient and digital solutions;
acquire or license products or technologies including through acquisitions; and
finance our capital expenditures and general and administrative expenses.
Our present and future funding requirements will depend on many factors, including:
the level of research and development investment required to develop our new solutions;
costs of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;
our need or decision to acquire or license complementary technologies or acquire complementary businesses;
changes in test development plans needed to address any difficulties in commercialization;
competing technological and market developments;
whether our diagnostic solutions become subject to additional FDA or other regulation; and
changes in regulatory policies or laws that affect our operations.

Additional capital, if needed, may not be available on satisfactory terms, or at all.all, and might include the issuance of equity securities, debt, cash from collaboration agreements, or a combination of these. Furthermore, if we raise additional funds by issuing equity securities, dilution to our existing stockholders could result. Any equity securities issued also may provide for rights, preferences or privileges senior to those of holders of our common stock and would result in dilution to our stockholders. Moreover, we have the ability to sell up to $200.0 million of additional shares of our common stock to the public through an “at the market” offering pursuant to thea Sales Agreement we entered into with Jefferies, LLC on April 14, 2022. Any shares of common stock issued in the at-the-market offering will result in dilution to our existing stockholders. If we raise additional funds by issuing debt securities, these debt securities would have rights, preferences and privileges senior to those of holders of our common stock, and the terms of the debt securities issued could impose significant restrictions on our operations. If we raise additional funds through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or our solutions under development, or grant licenses on terms that are not favorable to us, which could lower the economic value of those programs to us. If adequate funds are not available, we may have to scale back our operations or limit our research and development activities, which may cause us to grow at a slower pace, or not at all, and our business could be adversely affected.
We rely extensively on third party service providers. Failure of these parties to perform as expected, or interruptions in our relationship with these providers or their provision of services or supplies to us, could interfere with our ability to provide testOur operating results for our testing services businessmay be adversely affected by unfavorable economic and kits for our products business.market conditions.
Our relationship with any of our third party service providers may impair our ability to perform our services. The failure of any of our third party service providers to adequately perform their service obligations may reduce our revenues and increase our expenses or prevent us from providing our products and services in a timely manner if at all. In addition, our reputation, business and financial performance could be materially harmed if we are unable to, or are perceived as unable to provide test kits and perform reliable services.
We rely solely on certain suppliers to supply someMany of the laboratory instrumentscountries in which we operate, including the U.S. and key reagents that we use inseveral of the productionmembers of our products and/the European Union, or inEU, have experienced and continue to experience uncertain economic conditions resulting from global as well as local factors. On June 23, 2016, the performance of our tests. These sole source suppliers include Thermo Fisher,United Kingdom, or the UK, held a referendum pursuant to which supplies us with instruments, laboratory reagents and consumables; Roche Molecular Systems, which supplies us with laboratory reagents and consumables; Illumina, Inc., or Illumina, which supplies us with instruments, laboratory reagents, and consumables; Avantor, which supplies us with kitting services, laboratory reagents and consumables; Becton, Dickinson and Company, and Streck, which supplies us with cell preparation tubes; Beckman Coulter, which provides laboratory reagents and consumables; and Qiagen N.V., which supplies us with a proprietary buffer reagent and reagent kits. We do not have guaranteed supply agreements with Thermo Fisher, Becton, Dickinson and Company or Avantor, which exposes usvoters elected to leave the risk that these suppliers may choose to discontinue doing business with us at any time. We periodically forecast our needs to these sole source suppliers and enter into standard purchase orders based on these forecasts.
In addition, our ABI 7900 Thermocycler, a real time PCR instrument used in AlloMap Heart, is no longer in production. Thermo Fisher has committed to provide service and support of this instrument through 2022. We believe that there areEU, commonly

relatively few suppliersreferred to as Brexit. The UK formally left the EU on January 31, 2020 and began a transition period that ended on December 31, 2020. Although the ultimate effects of Brexit have yet to be seen, and the UK is in the process of negotiating trade deals with other than Thermo Fisher, Roche, Illumina, Becton, Dickinsoncountries, Brexit has created additional uncertainties that may ultimately result in new regulatory costs and Companychallenges for companies and Qiagen N.V.increased restrictions on imports and exports throughout Europe, which could adversely affect our ability to conduct and expand our operations in Europe and which may have an adverse effect on our business, financial condition and results of operations. Additionally, Brexit may increase the possibility that are currently capableother countries may decide to leave the EU in the future.
Our business or financial results may be adversely impacted by these uncertain economic conditions, including: adverse changes in interest rates, foreign currency exchange rates, tax laws or tax rates; increased inflation globally and in the U.S. in particular; the government closure of supplyingSilicon Valley Bank and potential liquidity concerns at other financial institutions; a potential economic recession; contraction in the instruments, reagentsavailability of credit in the marketplace due to legislation or other economic conditions, which may potentially impair our ability to access the capital markets on terms acceptable to us or at all; and other supplies necessarythe effects of government initiatives to manage economic conditions. A severe or prolonged economic downturn, such as the global financial crisis, could result in a variety of risks to our business, including a decrease in the demand for our current productstests and services. Even if we werein our ability to identify secondary suppliers, there can be no assurance that we will be able to enter into agreements with such suppliers on a timely basisraise additional capital when needed on acceptable terms, if at all. If we should encounter delays or difficulties in securing from Thermo Fisher, Becton, Dickinson and Company or Avantor, or Avantor encounters delays or difficulties in securing from Qiagen N.V., including as a result of impacts on their respective businesses due to the COVID-19 pandemic or the ongoing conflict between Ukraine and Russia and the global impact of restrictions and sanctions imposed on Russia, the quality and quantity of reagents, supplies or instruments that we require for our current products and services or other solutions we develop, we may need to reconfigure our test processes, which would result in delays in commercialization or an interruption in sales. Clinicians and customers who order our current products and services rely on the continued and timely availability of our products and services. If we are unable to provide results within a timely manner, clinicians may elect not to use our products or services in the future and our business and operating results could be harmed.
International expansion of our business exposes us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.
As part of our longer-term growth strategy, we intend to target select international markets to grow our presence outside of the U.S. We also currently distribute products directly in Germany, UK, New Zealand, Sweden, Austria, Belgium, Netherlands and Australia and sell products via sub-distributors, in Canada and in significant markets in Europe such as France, Italy, UK and Turkey, and to certain countries in Asia, the Middle East, and Central and South America. To promote the growth of our business internationally, we will need to attract additional partners to expand into new markets. 
Relying on partners for our sales and marketing subjects us to various risks, including:
our partners may fail to commit the necessary resources to develop a market for our products, may spend the majority of their time selling products unrelated to ours, or may be unsuccessful in marketing our products for other reasons;
under certain agreements, our partners’ obligations, including their required level of promotional activities, may be conditioned upon our ability to achieve or maintain a specified level of reimbursement coverage;
agreements with our partners may terminate prematurely due to disagreements or may result in disputes or litigation with our partners;
we may not be able to renew existing partner agreements, or enter into new agreements, on acceptable terms;
our existing relationships with partners may preclude us from entering into additional future arrangements;
our partners may violate local laws or regulations, potentially causing reputational or monetary damage to our business;
our partners may engage in sales practices that are locally acceptable but do not comply with standards required under U.S. laws that apply to us; and
our partners may be negatively affected by the financial instability of, and austerity measures implemented by, the countries in which they operate.
If our present or future partners do not perform adequately, or we are unable to enter into agreements in new markets, we may be unable to achieve revenue growth or market acceptance in jurisdictions in which we depend on partners. In addition, conducting international operations subjects us to risks that, generally, we have not faced in the U.S., including:
uncertain or changing regulatory registration and approval processes;
failure by us to obtain regulatory approvals or adequate reimbursement for the use of our current and future solutions in various countries;
competition from companies located in the countries in which we offer our products that may put us at a competitive disadvantage;
financial risks, such as longer accounts receivable payment cycles and difficulties in collecting accounts receivable;
logistics and regulations associated with shipping recipient samples, including infrastructure conditions and transportation delays;
limits in our ability to penetrate international markets if we are not able to process solutions locally;
53

Table of Contents
difficulties in managing and staffing international operations and assuring compliance with foreign corrupt practices laws;
potentially adverse tax consequences, including the complexities of foreign value added tax systems, tax inefficiencies related to our corporate structure and restrictions on the repatriation of earnings;
increased financial accounting and reporting burdens and complexities;
multiple, conflicting and changing laws and regulations such as healthcare regulatory requirements and other governmental approvals, permits and licenses;
the imposition of trade barriers such as tariffs, quotas, trade wars, preferential bidding or import or export licensing requirements;
political and economic instability, including interruptions in international relations, wars, terrorism and political unrest, general security concerns, outbreak of disease, boycotts, curtailment of trade and other business restrictions, including the ongoing conflict between Ukraine and Russia and the global impact of restrictions and sanctions imposed on Russia;
fluctuations in currency exchange rates;
regulatory and compliance risks that relate to maintaining accurate information and control over activities that may fall within the purview of the Foreign Corrupt Practices Act of 1977, its books and records provisions or its anti-bribery provisions, as well as risks associated with other anti-bribery and anti-corruption laws; and
reduced or varied protection for intellectual property rights in some countries.
The occurrence of any one of the above could harm our business and, consequently, our revenues and results of operations. Our expanding international operations could be affected by changes in laws, trade regulations, labor and employment regulations, and procedures and actions affecting approval, production, pricing, reimbursement and marketing of our current and future products and solutions, as well as by inter-governmental disputes. Any of these changes could adversely affect our business. Additionally, operating internationally requires significant management attention and financial resources. We cannot be certain that the investment and additional resources required in establishing operations in other countries will produce desired levels of revenue or profitability.
In addition, any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of shipments, and restrictions on certain business activities. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our distribution and sales activities.
We are also unable to predict how changing globalfuture economic conditions or potential global health concerns such as the COVID-19 pandemic will affect our partners,critical customers, suppliers and distributors. Anydistributors and any negative impact of such matters on our partners,critical customers, suppliers or distributors may also have an adverse impact on our results of operations or financial condition. We cannot anticipate all of the ways in which the foregoing, and the current economic climate and financial market conditions generally, could adversely impact our business.
Our success expanding internationally will depend, in part, oncurrent or future restructuring plans, including our abilityrecent decision to develop and implement policies and strategies that are effective in anticipating and managing these and other risks in the countries in which we do business. Failure to manage these and other risks may have a material adverse effect ondiscontinue our operations in any particular countryFremantle, Australia, may not optimize costs and onsimplify our organizational and corporate structure and may materially impair our business asoperations.
In January 2023, we announced a whole.restructuring plan intended to optimize costs and simplify our organizational and corporate structure. Our restructuring plan includes the discontinuation of our operations in Fremantle, Australia, terminating our employees in that location and vacating our facilities there. The winding down of our operations in Australia has, and any additional restructuring efforts may, divert management's attention, increase expenses on a short term basis and lead to potential issues with employees, customers, or suppliers. If we do not complete these activities in a timely manner; or do not realize anticipated cost savings, synergies and efficiencies; or business disruption occurs during or following such activities; or we incur unanticipated charges, our business, financial condition, operating results, and cash flows may be materially impaired.
Risks Related to Billing and Reimbursement
Billing complexities associated with obtaining payment or reimbursement for our current and future solutions may negatively affect our revenue, cash flows and profitability.
Billing for clinical laboratory testing services is complex. In cases where we do not have a contract in place requiring the Healthcare Regulatory Environment
In order to operate our laboratory,payment of a fixed fee per test, we have to comply with the CLIAperform tests in advance of payment and federal state laws and regulations governing clinical laboratories and laboratory developed tests, including FDA regulations.
We are subjectwithout certainty as to the CLIA,outcome of the billing process. In cases where we do receive a federal law that regulates clinical laboratories that perform testing on specimens taken from humans for the purpose of providing information for the diagnosis, prevention or treatment of disease. If our laboratory is out of compliance with the CLIA requirements,fixed fee per test, we may be subject to sanctionsstill have disputes over pricing and billing. We receive payment from individual recipients and from a variety of payers, such as suspension, limitationcommercial insurance carriers and governmental programs, primarily Medicare. Each payer typically has different billing requirements.
Among the factors complicating our billing of third-party payers are:
disputes among payers regarding which party is responsible for payment;
disparity in coverage among various payers;
different process, information and billing requirements among payers; and
incorrect or revocationmissing billing information, which is required to be provided by the prescribing clinician.

See the discussion of the Billing Articles under the risk factor above titled "Health insurers and other third-party payers may decide to revoke coverage of our CLIA certificate, as well as a direct plan of correction, state on-site monitoring, civil money penalties, civil injunctive suit or criminal penalties. We must maintain the CLIA compliance and certificationexisting test, decide not to be eligible to bill for services provided to Medicare beneficiaries. If we were to be found to be out of compliance with the CLIA program requirements and subjected to sanction,cover our business could be materially harmed.
Licensure is also required for our laboratory under California law in order to conduct testing. California laws establish standards for day-to-day operation of our clinical laboratory, including the training and skills required of personnel and quality control. Moreover, several states, including New York, require that we hold licenses to test specimens from patients residing in those states. Other states have similar requirementsfuture solutions or may adopt similarprovide inadequate reimbursement, which could jeopardize our commercial prospects".
Additionally, from time to time, payers change processes that may affect timely payment. For example, some commercial payers have instituted prior authorization requirements before our testing is performed. These changes may result in uneven cash flow or impact the future. In additiontiming of revenue recognized with these payers. With respect to our California certifications, we currently hold licenses in Florida, Maryland, New York, Pennsylvania and Rhode Island. The losspayments received from governmental

programs, factors such as a prolonged government shutdown could cause significant regulatory delays or could result in attempts to reduce payments made to us by federal government healthcare programs. In addition, payers may refuse to ultimately make payment if their processes and requirements have not been met on a timely basis. In addition, we are subject to and expect to continue to be subject to one or more audits under the CMS Recovery Audit Contractor, or RAC, program, the CMS Targeted Probe and Educate, or TPE, program, the Unified Program Integrity Contractors, or UPIC, program and other federal and state audits. Following two rounds of anyTPE audit in which AlloSure Kidney and AlloSure Heart claims were reviewed and denied, Noridian informed us it was making a referral to CMS given disagreement as to the interpretation of the applicable LCDs. We appealed claims which had a basis for appeal and those claims were denied. We continue to pursue appeals of these state certifications would impactclaims consistent with our abilitystatutory rights. We have met with CMS to providediscuss the difference in interpretation and intend to continue this dialogue regarding our position that the Noridian interpretation is inconsistent with the LCD, MolDX’s and Noridian’s prior associated responses to public comments, and medical necessity.We expect further intensification of the regulatory environment surrounding the healthcare industry, as third-party firms engaged by CMS and others conduct extensive pre and post-payment audits of claims data as well as medical and other records in order to identify improper payments to healthcare providers under the Medicare and Medicaid programs. We could be forced to expend considerable resources responding to these audits or other inquiries. These billing complexities, and the resulting uncertainty in obtaining payment for AlloSure Kidney, AlloMap Heart, AlloSure Heart and future solutions, as well as the results of Noridian's referral to CMS and any audits or inquiries evaluating the medical necessity of our services in those states, whichcreates a risk that our claims are denied or that any historical reimbursement of such claims is subject to forfeiture and could negatively affect our business.
Finally, we may be subject to regulation in foreign jurisdictions where we offer our test. Failure to maintain certification in those states or countries where it is required could prevent us from testing samples from those states or countries, could lead to the suspension or loss of licenses, certificates or authorizations,revenue, cash flows and could have an adverse effect on our business.
We were inspected as part of the customary College of American Pathologists audit and recertified in March 2022 as a result of passing that inspection. We expect the next regular inspection under the CLIA to occur in 2024.
If we were to lose our CLIA accreditation or California license, whether as a result of a revocation, suspension or limitation, we would no longer be able to perform AlloMap Heart, AlloSure Kidney or AlloSure Heart, which would limit our revenues and materially harm our business. If we were to lose our license in other states where we are required to hold licenses, we would not be able to test specimens from those states, which could also have a material adverse effect on our business.
The FDA has traditionally chosen not to exercise its authority to regulate laboratory developed tests, or LDTs, because it believes that laboratories certified as high complexity under the CLIA, such as ours, have demonstrated expertise and ability in test procedures and analysis. However, beginning in September 2006, the FDA issued draft guidance on a subset of LDTs known as “in vitro diagnostic multivariate index assays,” or IVDMIAs. According to the draft guidance, IVDMIAs do not fall within the scope of LDTs over which the FDA has exercised enforcement discretion because such tests incorporate complex and unique interpretation functions, which require clinical validation. We believed that AlloMap Heart met the definition of IVDMIA set forth in the draft guidance document. As a result, we applied for, and obtained in August 2008, 510(k) clearance for AlloMap Heart for marketing and sale as a test to aid in the identification of recipients with a low probability of moderate or severe rejection. A 510(k) submission is a premarketing submission made to the FDA. Clearance may be granted by the FDA if it finds the device or test provides satisfactory evidence pertaining to the claimed intended uses and indications for the device or test.
While we believe that we are currently in material compliance with applicable laws and regulations relating to our LDTs, we cannot be certain that the FDA or other regulatory agencies would agree with our determination. A determination that we have violated these laws, or a public announcement that we are being investigated for possible violation of these laws, could hurt our business and our reputation.

profitability.
We are subject to numerous fraud and abuse and other laws and regulations pertaining to our business, the violation of any one of which could harm our business.
The clinical laboratory testing industry is highly regulated, and there can be no assurance that the regulatory environment in which we operate will not change significantly and adversely in the future. Our arrangements with customers may expose us to broadly applicable fraud and abuse and other laws and regulations that may restrict the financial arrangements and relationships through which we market, sell and distribute our products and services. Our employees, consultants, principal investigators, advisors and commercial partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements. In addition to the CLIA regulation, other federal and state healthcare laws and regulations that may affect our ability to conduct business, include, without limitation:
federal and state laws and regulations regarding billing and claims payment applicable to clinical laboratories and/or regulatory agencies enforcing those laws and regulations;
federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented to the government, claims for payment from Medicare, Medicaid or other third-party payers that are false or fraudulent, or making a false statement material to a false or fraudulent claim;
the federal Anti-Kickback Statute, which constrains our marketing practices, educational programs, pricing policies, and relationships with healthcare providers or other entities, by prohibiting, among other things, knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce or reward, or in return for, either the referral of an individual or the purchase or recommendation of an item or service reimbursable under a federal health care program, such as the Medicare and Medicaid programs;
the federal physician self-referral law, commonly known as the Stark Law, which prohibits a physician from making a referral to an entity for certain designated health services, including clinical laboratory services, reimbursed by Medicare if the physician (or a member of the physician’s family)
has a financial relationship with the entity, and which also prohibits the submission of any claims for reimbursement for designated health services furnished pursuant to a prohibited referral;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and its implementing regulations, which imposes certain requirements relating to the privacy, security and

Table of Contents
transmission of individually identifiable health information; HIPAA also created criminal liability for knowingly and willfully falsifying or concealing a material fact or making a materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;
state laws regarding prohibitions on fee-splitting;
the federal health care program exclusion statute; and
state and foreign law equivalents of each of the above federal laws and regulations, such as anti-kickback, false claims, and self-referral laws, which may apply to items or services reimbursed by any third-party payer, including commercial insurers, and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.
Because of the breadth of these laws and the narrowness of available statutory and regulatory exemptions, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Any action brought against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. We may be subject to private “qui tam” actions brought by individual whistleblowers on behalf of the federal or state governments, with potential liability under the federal False Claims Act, including mandatory treble damages and significant per-claim penalties. We previously received a civil investigative demand (CID) from the United States Department of Justice (DOJ) requesting that we produce certain documents in connection with a False Claims Act investigation being conducted by the DOJ regarding certain business practices related to our kidney testing and phlebotomy services, and a subpoena from the SEC in relation to an investigation by the SEC in respect of matters similar to those identified in the CID, as well as certain of our accounting and public reporting practices. We also previously received an information request from a state regulatory agency and may receive additional requests for information from the DOJ, SEC, or other regulatory and governmental agencies regarding similar or related subject matters. We do not believe that the CID, the SEC subpoena or the state regulatory agency information request raise any issues regarding the safety or clinical utility of any of our products or services and are cooperating fully with the investigations. Although we remain committed to compliance with all applicable laws and regulations, we cannot predict the outcome of the DOJ or SEC investigations, the state regulatory agency information request, or any other requests or investigations that may arise in the future regarding these or other subject matters. If our operations are found to be in violation of any of the federal, state and foreign laws described above or any other current or future fraud and abuse or other laws and regulations that apply to us, we may be subject to penalties, including significant criminal, civil, and administrative penalties, damages, fines, imprisonment for individuals, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, if any governmental body, such as the DOJ or SEC, determines that we have not complied with applicable securities or other laws, such governmental body could initiate a proceeding against us, which may ultimately lead to significant penalties and other relief assessed against us, including monetary fines. We may expend significant financial and managerial resources in connection with responding to the CID, the SEC subpoena and other information requests. Any of the foregoing consequences could seriously harm our business and our financial results.
In addition, we have implemented and strive to continuously develop, implement and improve compliance policies and procedures intended to train our sales, billing, marketing and other personnel regarding compliance with state and federal laws applicable to our business. Our efforts to implement appropriate monitoring of compliance with such policies and procedures are likewise ongoing. We may need to supplement and amend our current policies and procedures and implement additional policies and procedures in the future. In addition, despite our compliance policies and procedures, and related training and monitoring, we may experience situations in which employees may fail to fully adhere to our policies and procedures. Such failures may subject us to administrative, civil, and criminal actions, penalties, damages, fines, exclusion from participation in federal health care programs, refunding of payments received by us and curtailment of our operations.
Risks Related to Our Intellectual Property
Our competitive position depends on maintaining intellectual property protection.
Our ability to compete and to achieve and maintain profitability depends on our ability to protect our proprietary discoveries and technologies. We currently rely on a combination of patents, copyrights, trademarks, trade secrets, confidentiality agreements and license agreements to protect our intellectual property rights.
Our patent position for AlloMap Heart is based on issued patents and patent applications disclosing identification of genes differentially expressed between activated and restingquiescent leukocytes and demonstration of correlation between gene expression patterns and specific clinical states and outcomes. As of September 30, 2022,March 31, 2023, we had 20 issued U.S. patents related to transplant rejection and autoimmunity. Among those, we have twoone issued U.S. patentspatent covering methods of diagnosing transplant rejection using all 11 informative genes measured in AlloMap Heart. The expiration dates of these patents range from 2023 toHeart, which will expire in March 2024. We have four additional patents covering additional genes or gene variants for diagnosing transplant rejection or autoimmune disease.
56

Table of Contentsdisease, which will expire between August 2024 and September 2029.
In connection with our June 2014 acquisition of ImmuMetrix, Inc., we obtained an exclusive license from Stanford to one U.S. patent issued in April 2014 relating to the diagnosis of rejection in organ transplant recipients using dd-cfDNA. Additional patents from Stanford included in the exclusive license were issued, including one in 2017, two in 2019, and four in 2021, two in 2022 and one in 2023, that further cover the use of dd-cfDNA to diagnose and predict transplant status or outcome. These patents are expiringwill expire between 2030 and 2032.
Our patents and the patents we exclusively license from others may be successfully challenged by third parties as being invalid or unenforceable. For example, in September 2021, the Court in the patent infringement case against Natera ruled that three of the patents we asserted against Natera are invalid. The Court’s finding does not have any impact on our ability to continue providing AlloSure, and we have appealed the decision.AlloSure. This ruling may limit our ability to prevent Natera and other competitors and third parties from developing and marketing products similar to ours and we may not be able to prevent Natera and others from developing or selling products that are covered by our products or technologies, without payment to us. On March 29, 2023, we entered into an agreement with Stanford whereby we agreed, among other things, to seek a review from the United States Supreme Court, or the Review. During the pendency of the Review, certain of our licensing payment and reporting obligations to Stanford with respect to licensed products sold in the U.S., and our right to terminate the Exclusive Agreement upon 30 days’ advance notice to Stanford, are suspended. However, there can be no assurance that the Review will be granted or that any decision by the Supreme Court will be granted in our favor. Third parties may independently develop similar or competing technology that avoids the patents we own or exclusively license. We cannot be certain that the steps we have taken will prevent the misappropriation and use of our intellectual property, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.
The extent to which the patent rights of life sciences companies effectively protect their products and technologies is often highly uncertain and involves complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the proper scope of allowable claims of patents held by such companies has emerged to date in the United States. Various courts, including the United States Supreme Court, have rendered decisions that impact the scope of
60

Table of Contents
patentability of certain inventions or discoveries relating to diagnostic solutions or genomic diagnostics. In the Ariosa Diagnostics, Inc. v. Sequenom, Inc. (Fed. Cir. 2015) case, a federal court recently determined that a cfDNA product for fetal testing was not eligible for patent protection. These decisions generally stand for the proposition that inventions that recite laws of nature are not themselves patentable unless they have sufficient additional features that provide practical assurance that the processes are genuine inventive applications of those laws rather than patent drafting efforts designed to monopolize a law of nature itself. What constitutes a “sufficient” additional feature for this purpose is uncertain. This evolving case law in the United States may adversely impact our ability to obtain new patents and may facilitate third-party challenges to our existing owned and exclusively licensed patents.
Changes in either the patent laws or in interpretations of patent laws in the United States or other countries may diminish the value of our intellectual property rights. In particular, in September 2011, the United States Congress passed the Leahy-Smith America Invents Act, or the AIA, which became effective in March 2013. The AIA reforms United States patent law in part by changing the standard for patent approval for certain patents from a “first to invent” standard to a “first to file” standard and developing a post-grant review system. This has not yet had a material impact on the operation of our business and the protection and enforcement of our intellectual property, but it may in the future. The AIA and its implementation could still increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition. Patent applications in the United States and many foreign jurisdictions are not published until at least eighteen months after filing, and it is possible for a patent application filed in the United States to be maintained in secrecy until a patent is issued on the application. In addition, publications in the scientific literature often lag behind actual discoveries.
We therefore cannot be certain that others have not filed patent applications that cover inventions that are the subject of pending applications that we own or exclusively license or that we or our licensors, as applicable, were the first to invent the technology (pre-AIA) or first to file (post-AIA). Our competitors may have filed, and may in the future file, patent applications covering technology that is similar to or the same as our technology. Any such patent application may have priority over patent applications that we own or exclusively license and, if a patent issues on such patent application, we could be required to obtain a license to such patent in order to carry on our business. If another party has filed a United States patent application covering an invention that is similar to, or the same as, an invention that we own or license, we or our licensors may have to participate in an interference or other proceeding in the PTO or a court to determine priority of invention in the United States for pre-AIA applications and patents.
For post-AIA applications and patents, we or our licensors may have to participate in a derivation proceeding to resolve disputes relating to inventorship. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful, resulting in our inability to obtain or retain any United States patent rights with respect to such invention.
We may face intellectual property infringement claims that could be time-consuming and costly to defend and could result in our loss of significant rights and the assessment of treble damages.

We may in the future receive offers to license patents or notices of claims of infringement, misappropriation or misuse of other parties’ proprietary rights. We may also initiate claims to defend our intellectual property. Intellectual property litigation, regardless of outcome, is unpredictable, expensive and time-consuming, could divert management’s attention from our business and have a material negative effect on our business, operating results or financial condition. If there is a successful claim of infringement against us, we may be required to pay substantial damages (including treble damages if we were to be found to have willfully infringed a third party’s patent) to the party claiming infringement, develop non-infringing technology, stop selling our test or using technology that contains the allegedly infringing intellectual property or enter into royalty or license agreements that may not be available on acceptable or commercially practical terms, if at all. Our failure to develop non-infringing technologies or license the proprietary rights on a timely basis could harm our business.
In addition, revising our current or future solutions to exclude any infringing technologies would require us to re-validate the test, which would be costly and time consuming. Also, we may be unaware of pending patent applications that relate to our current or future solutions. Parties making infringement claims on future issued patents may be able to obtain an injunction that would prevent us from selling our current or future solutions or using technology that contains the allegedly infringing intellectual property, which could harm our business. For example, see the risk factor above titled: “We could become subject to legal proceedings that could be time consuming, result in costly litigation and settlements/judgments, require significant amounts of management attention and result in the diversion of significant operational resources, which could adversely affect our business, financial condition and results of operations” for a discussion of our recently completed and ongoing litigation with Natera.
We may be required to take further action to maintain and protect our intellectual property rights against third parties.
In the event we determine that a party is infringing our intellectual property rights, we may try to negotiate a license arrangement with such party or we may determine to initiate a lawsuit against such party. The process of negotiating a license with a third party can be lengthy, and may take months or even years in some circumstances. In addition, it is possible that third parties who we believe are infringing our intellectual property rights are unwilling to license our intellectual property from us on terms we can accept, or at all. For example, see the risk factor above titled: “We could become subject to legal proceedings that could be time consuming, result in costly litigation and settlements/judgments, require significant amounts of management attention and result in the diversion of significant operational resources, which could adversely affect our business, financial condition and results of operations” for a discussion of our recently completed and ongoing litigation with Natera.
The decision to commence litigation over infringement of a patent is complex and may lead to several risks to us, including the following, among others:
the time, significant expense and distraction to management of managing such litigation;
the uncertainty of litigation and its potential outcomes;
the possibility that in the course of such litigation, the defendant may challenge the validity of our patents, which could result in a re-examination or post grant review of our patents and the possibility that the claims in our patents may be limited in scope or invalidated altogether;
the potential that the defendant may successfully persuade a court that their technology or products do not infringe our intellectual property rights;
the impact of such litigation on other licensing relationships we have or seek to establish, including the timing of renewing or entering into such relationships, as applicable, as well as the terms of such relationships;
the potential that a defendant may assert counterclaims against us; and
adverse publicity to us or harm to relationships we have with customers or others.
Our business is dependent on licenses from third parties.
We license technology from third parties necessary to develop and commercialize our products. In connection with our acquisition of ImmuMetrix, Inc., we obtained an exclusive license from Stanford to one U.S. patent issued in April 2014 relating to the diagnosis of rejection in organ transplant recipients using dd-cfDNA. This technology is critical to AlloSure Kidney under the terms of the Stanford license, we are required to pay certain fees. Additional patents from Stanford included in the exclusive license were issued, including one in 2017, two in 2019, and four in 2021 that further cover the use of dd-cfDNA to diagnose and predict transplant status or outcome. These patents are expiring between 2030 and 2032.
On May 4, 2018, we entered into the License Agreement with Illumina, which provides us with worldwide distribution, development and commercialization rights to Illumina’s NGS product line for use in transplantation diagnostic testing. As a result, on June 1, 2018, we became the exclusive worldwide distributor of Illumina’s TruSight HLA product line.

Table of Contents
On April 30, 2019, we entered into the Cibiltech Agreement, pursuant to which we were granted an irrevocable, non-transferable right to commercialize Cibiltech’s proprietary software, iBox, for the predictive analysis of post-transplantation kidney allograft loss in the field of transplantation in the U.S. for a period of ten years.
In April 2020, we entered into a license agreement with Cornell University pursuant to which we were granted exclusive rights to three patents and two patent applications covering methods and technology for measurement of gene expression in urine to diagnose kidney transplant rejection.
In June 2021, we entered into a strategic agreement, which was amended in April 2022, with OrganX to develop clinical decision support tools across the transplant patient journey. Together, we and OrganX will develop advanced analytics that integrate AlloSure, the first transplant specific dd-cfDNA assay, with large transplant databases to provide clinical data solutions. This partnership delivers the next level of innovation beyond multi-modality by incorporating a variety of clinical inputs to create a universal composite scoring system.
Our rights to use this and other licensed technologies, data and materials and to employ the inventions claimed in licensed patents are subject to the continuation of and our compliance with the terms of the applicable licenses.
Termination of the license could prevent us from producing or selling some or all of our products. Failure of a licensor to abide by the terms of a license or to prevent infringement by third parties could also harm our business and negatively impact our market position.
Risks Related to Cybersecurity
We face four primary risks relative to protecting critical information: loss of access risk, inappropriate disclosure risk, inappropriate modification risk and the risk of our being unable to identify and audit our controls over the first three risks. In addition, an application, data security or network incident may allow unauthorized access to our systems or data or our customers’ data, disable access to our service, harm our reputation, create additional liability and adversely impact our financial results.
We are highly dependent on information technology networks and systems, including the Internet, to securely process, transmit and store our critical information. Security breaches of this infrastructure, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure or modification of confidential information. The secure processing, storage, maintenance and transmission of this critical information are vital to our operations and business strategy, and we devote significant resources to protecting such information. Although we take measures to protect sensitive information from unauthorized access or disclosure, our information technology and infrastructure may be vulnerable to attacks by hackers or viruses or breached due to employee error, malfeasance or other disruptions. In addition, as a result of the COVID-19 pandemic, we may face increased cybersecurity risks due to our reliance on internet technology which may create additional opportunities for cybercriminals to exploit vulnerabilities. While we maintain monitoring practices and protections for our information technology to reduce these risks and test our systems on an ongoing basis for any potential threats, there can be no assurance that these efforts will prevent a cyber-attack or other security breach.
Third parties have attempted, and may in the future attempt, to fraudulently induce employees, contractors or consumers into disclosing sensitive information such as user names, passwords or other information or otherwise compromise the security of our internal networks, electronic systems and/or physical facilities in order to gain access to our data or our critical information, which could result in significant legal and financial exposure. We have experienced cybersecurity incidents and expect that we will continue to be subject to cybersecurity attacks in the future. In addition, a contractor or other third party with whom we do business, as well as parties with which we do not do business, may attempt to circumvent our security measures or obtain such information, and may purposefully or inadvertently cause a breach involving sensitive information. While we still continue to evaluate and implement additional protective measures to reduce the risk and detect cyber incidents, cyberattacks are becoming more sophisticated and frequent and the techniques used in such attacks change rapidly. Despite our cybersecurity measures (including employee and third party training regarding phishing, malware, and other cyber risks, monitoring of networks and systems and maintenance of back up of protective systems), which are continuously reviewed and upgraded, our information technology networks and infrastructure may still be vulnerable to damage, disruptions or shut downs due to attack by hackers or breaches, phishing scams, ransomware, systems failures, computer viruses, employee errors or other malfeasance. A security breach or privacy violation that leads to disclosure or modification of or prevents access to consumer information (including personally identifiable information or protected health information) could harm our reputation, compel us to comply with disparate state breach notification laws, require us to verify the correctness of database contents and otherwise subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue. If we are unable to prevent such security breaches or privacy violations or implement satisfactory remedial measures, our operations could be disrupted, and we may suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated information,

including sensitive consumer data. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above.
Any such breach or interruption could compromise our networks or those of our third-party billing agent, and the information stored there could be inaccessible or could be accessed by unauthorized parties, publicly disclosed, lost or stolen. Any such interruption in access, improper access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, such as the Health Insurance Portability and Accountability Act of 1996, or HIPAA, and regulatory penalties. Unauthorized access, loss or dissemination could also disrupt our operations, including our ability to perform tests, provide test results, bill our payers or patients, process claims and appeals, provide customer assistance services, conduct research and development activities, collect, process and prepare company financial information, provide information about our current and future products and solutions and other patient and clinician education and outreach efforts through our website, and manage the administrative aspects of our business, any of which could damage our reputation and adversely affect our business. Any such breach could also result in the compromise of our trade secrets and other proprietary information, which could adversely affect our competitive position. We have insurance coverage in place for certain potential liabilities and costs relating to service interruptions, data corruption, cybersecurity risks, data security incidents and/or network security breaches, but this insurance is limited in amount, subject to a deductible, and may not be adequate to cover us for all costs arising from these incidents. Furthermore, in the future such insurance may not be available on commercially reasonable terms, or at all.
In addition, the interpretation and application of consumer, health-related, privacy and data protection laws in the U.S., Europe and elsewhere are often uncertain, contradictory and in flux. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. If so, this could result in government-imposed fines or orders requiring that we change our practices, which could adversely affect our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices and compliance procedures in a manner adverse to our business. For example, the California Consumer Privacy Act, or the CCPA, took effect on January 1, 2020. The CCPA, among other things, requires covered companies to provide disclosures to California consumers concerning the collection and sale of personal information, and will give such consumers the right to opt-out of certain sales of personal information. The California Privacy Rights Act, or the CPRA, which will become effective on January 1, 2023, will significantly modify the CCPA, and also create a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA. The CCPA and the CPRA may increase our compliance costs and potential liability, and we cannot yet predict the impact of the CCPA or the CPRA on our business. Additionally, state legislation continues to be a driving force behind the changing privacy law landscape in the United States. For example, Virginia passed the Consumer Data Protection Act, Colorado passed the Colorado Privacy Act, Utah passed the Consumer Privacy Act, and Connecticut passed the Connecticut Data Privacy Act, all of which become effective in 2023. Internationally, the General Data Protection Regulation, or the GDPR, took effect in May 2018 within the European Economic Area, or the EEA, and many EEA jurisdictions have also adopted their own data privacy and protection laws in addition to the GDPR. Furthermore, other international jurisdictions, including Singapore, South Korea, China, Brazil, Mexico and Australia, have also implemented laws relating to data privacy and protection.
Risks Related to Our Common Stock
Our operating results may fluctuate, which could cause our stock price to decrease.
Fluctuations in our operating results may lead to fluctuations, including declines, in the share price for our common stock. From January 3, 20222023 to September 30, 2022,March 31, 2023, our closing stock price ranged from$16.06 $8.83 to $46.60$17.61 per share.share. Our operating results and our share price may fluctuate from period to period due to a variety of factors, including:
demand by clinicians and recipients for our current and future solutions, if any;
coverage and reimbursement decisions by third-party payers and announcements of those decisions;
clinical trial results and publication of results in peer-reviewed journals or the presentation at medical conferences;
the inclusion or exclusion of our current and future solutions in large clinical trials conducted by others;

Variations in the timing of our future revenues and expenses could also cause significant fluctuations in our operating results from period to period and may result in unanticipated earning shortfalls or losses. In addition, national stock exchanges, and in particular the market for life science companies, have experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Moreover, we may be subject to additional securities class action litigation as a result of volatility in the price of our common stock, which could result in substantial costs and diversion of management’s attention and resources and could harm our stock price, business, prospects, results of operations and financial condition.
The market price of our common stock has been and will likely continue to be volatile, and you could lose all or part of your investment.
Our common stock is currently traded on the Nasdaq Global Market, but we can provide no assurances that there will be active trading on that market or on any other market in the future. If there is no active market or if the volume of trading is limited, holders of our common stock may have difficulty selling their shares. From January 3, 2022 to September 30, 2022, our closing stock price ranged from $16.06 to $46.60 per share. The market price of our common stock has been and may continue to be subject to wide fluctuations in response to various factors, some of which are beyond our control. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2021,2022, filed with the SEC on February 24, 2022,27, 2023, factors that could cause fluctuations in the market price of our common stock include the following:
price and volume fluctuations in the overall stock market from time to time;
volatility in the market prices and trading volumes of life sciences stocks;
changes in operating performance and stock market valuations of other life sciences companies generally, or those in our industry in particular;
sales of shares of our common stock by us or our stockholders;
entering into financing or other arrangements with rights or terms senior to the interests of common stockholders;
failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;
the financial projections we may provide to the public, any changes in those projections or failure to meet those projections;
announcements by us or our competitors of new products or services;

General Risk FactorsIf our principal stockholders, executive officers and directors choose to act together, they may be able to control our management and operations, which may prevent us from taking actions that may be favorable to you.

The impactOur executive officers, directors and holders of the Russian invasion5% or more of Ukraineour outstanding common stock (based on the global economy, energy suppliesmost recent public filings), and raw materials is uncertain, but may proveentities affiliated with them, beneficially own in the aggregate approximately 62.1% of our common stock as of May 8, 2023. These stockholders, acting together, will have the ability to negatively impactexert substantial influence over all matters requiring approval by our stockholders, including the election and removal of directors and any proposed merger, consolidation or sale of all or substantially all of our assets. In addition, they could dictate the management of our business and operations.
The short and long-term implicationsaffairs. This concentration of Russia’s invasion of Ukraine are difficult to predict at this time. We continue to monitor any adverse impact that the outbreak of war in Ukraine and the subsequent institution of sanctions against Russia by the United States and several European and Asian countries may have on the global economy in general, on our business and operations and on the businesses and operations of our suppliers and customers. For example, a prolonged conflict may result in increased inflation, escalating energy prices and constrained availability, and thus increasing costs, of raw materials. We will continue to monitor this fluid situation and develop contingency plans as necessary to address any disruptions to our business operations as they develop. To the extent the war in Ukraine may adversely affect our business as discussed above, it may alsoownership could have the effect of heightening manydelaying, deferring or preventing a change in control of us or impeding a merger or consolidation, takeover or other business combination that could be favorable to you.
We may elect to repurchase shares of our common stock, which might limit our ability to pursue other growth opportunities.
On December 3, 2022, our board of directors authorized a stock repurchase program, whereby we may purchase up to $50 million in shares of our common stock over a period of up to two years, commencing on December 8, 2022, or the other risks described herein. Such risks include,Repurchase Program. The Repurchase Program may be carried out at the discretion of a committee of our Board of Directors through open market purchases, one or more Rule 10b5-1 trading plans, block trades and in privately negotiated transactions. Any repurchase of shares of our common stock under the Repurchase Program will depend on several factors, including, but are not limited to, adverse effectsresults of operations, capital requirements, financial conditions, available capital from operations or other sources, including debt, and the market price of our common stock. In addition, on macroeconomic conditions, including inflation; disruptionsAugust 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022, which, among other things, imposes an excise tax of 1% tax on the fair market value of net stock repurchases made after December 31, 2022. Therefore, there is no assurance with respect to the amount, price or timing of any such repurchases. We may elect to retain all future earnings for the operation and expansion of our global technology infrastructure, including through cyberattack, ransom attack, or cyber-intrusion; adverse changesbusiness, rather than repurchasing shares of our common stock.
During the three months ended March 31, 2023, we purchased an aggregate of 59,472 shares of our common stock under the Repurchase Program for an aggregate purchase price of $0.7 million. As of March 31, 2023, $48.7 million remained available for future share repurchase under the Repurchase Program.
In the event we make any additional stock repurchases in international trade policies and relations;the future, our ability to maintainfinance any material expansion of our business, including through acquisitions, investments or increaseincreased capital spending, or to fund our product prices; disruptions in global supply chains; our exposure to foreign currency fluctuations; and constraints, volatility, or disruptionoperations, may be limited. In addition, any repurchases we may make in the capital markets,future may not prove to be at optimal prices. Our Board of Directors may modify or amend the Repurchase Program, or adopt a new stock repurchase program, at any time at its discretion without stockholder approval.
We have identified material weaknesses in our internal control over financial reporting as of December 31, 2022. If we are unable to remediate these material weaknesses and maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner.
Effective internal control over financial reporting is necessary for us to provide reasonable assurance regarding the preparation and fair presentation of published consolidated financial statements in accordance with accounting principles generally accepted in the United States. In connection with the preparation of our consolidated financial statements as of December 31, 2022 and for the year then ended, we identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
Our management concluded that we had the following material weaknesses as of December 31, 2022:
General Information Technology Controls. We did not design and maintain effective general information technology controls (“GITCs”), for information systems and applications that are relevant to the preparation of the consolidated financial statements. Specifically, we did not design and maintain: (i) sufficient user access controls to ensure appropriate segregation of duties, logical access controls to prevent unauthorized user access and adequately restrict user and privileged access to financial applications, programs and data to appropriate Company personnel; (ii) program change management controls to ensure that information technology (“IT”), program and data changes affecting financial IT applications and underlying accounting records are identified, tested, authorized and implemented appropriately with appropriate segregation of duties; and (iii) Computer and Network operations controls to ensure that batch and interface jobs are monitored and privileges are appropriately granted, authorized and monitored. As a result, business process controls (automated and manual) that are dependent on the ineffective GITCs, or that rely on data produced from systems impacted by the ineffective GITCs, are also deemed ineffective, which affects substantially all financial statement account balances and disclosures.

Table of Contents
Purchase Order Approval Workflow. We did not design and maintain effective process-level control activities related to procurement to ensure appropriate approval of purchase orders, which could negatively affect the amount and classification of costs capitalized or expensed.
Committee of Sponsoring Organizations of the Treadway Commission (COSO) Framework. We did not fully maintain components of the COSO framework, including elements of the control environment, information and communication, and control activities and monitoring activities components, relating to: (i) sufficiency of competent personnel to perform internal control activities and support the achievement of our businessinternal control objectives; (ii) enforcing accountability of personnel for the performance of their internal control responsibilities across the organization in the pursuit of objectives; (iii) designing and maintaining general control activities over technology to support the achievement of our internal control objectives; (iv) performing control activities in accordance with established policies in a timely manner; and (v) performing sufficient reviews of information to assess its relevance, accuracy, and completeness in supporting the internal control components. As such, our management concluded that we did not have an adequate process in place to complete its assessment of the design and operating effectiveness of internal control over financial condition.reporting in a timely manner.
These material weaknesses have not been remediated as of the date of this Quarterly Report on Form 10-Q. Our management has been engaged in developing and implementing remediation plans to address the material weaknesses described above. However, the material weaknesses will not be fully remediated until management can demonstrate the full effectiveness of controls over a sufficient period of time, and we can give no assurance on the success of such measures or the outcome of our assessment of these measures at this time.
If the steps we take to remediate the material weaknesses are ineffective, these material weaknesses could result in material misstatements to our annual or interim consolidated financial statements that might not be prevented or detected on a timely basis, or in delayed filings of our required periodic reports. This might lead to investors losing confidence in the accuracy and completeness of our financial reports, the market price of the common stock could be adversely affected, and we could become subject to litigation or investigations by The Nasdaq Stock Market LLC, the SEC or other regulatory authorities, which could require additional financial and management resources.
Furthermore, if we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to remediate our existing material weaknesses or avoid potential future material weaknesses.
