Revenue Recognition |
Revenue Recognition | 3. Revenue Recognition The Company recognizes revenues when, or as, performance obligations in the contracts are satisfied, in the amount reflecting the expected consideration to be received from the goods or services transferred to the customers. Product Revenues Product revenues are derived by performing genetic testing services and the Company’s performance obligation is complete when test results are delivered to a laboratory or patient (each a customer). Additionally, the Company enters into agreements with pharmaceutical companies to utilize the Company’s Signatera tests, typically to study new cancer treatments or to validate the outcomes of clinical trials for which the pharmaceutical companies are identified as customers. Such arrangements generally involve performing whole-exome sequencing services and the testing of patient samples to detect cancer mutations using its Signatera test. In addition to performing Signatera tests, these agreements typically include certain activities to fulfill the contract, such as customer data setup and management and ongoing reporting. Each test result is billable to customers upon delivery and the personalized cancer profile also makes each test distinct within the context of the contract as customers can exercise control over the test results upon delivery. Accordingly, the Company recognizes test processing revenue as individual test results are delivered to customers. For certain contracts with pharmaceutical companies where the Company is developing a companion diagnostic test in addition to performing regular testing services, revenue is primarily recognized proportionally as services are performed and/or tests are delivered. A performance obligation represents a promise in a contract to transfer a distinct good or service to a customer, which represents a unit of accounting in accordance with ASC 606. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance obligation satisfied once the Company has transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. A portion of the consideration should be allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The Company evaluates its contracts with laboratory partners and patients and identifies the performance obligations in those contracts, which are the delivery of the test results. The total consideration the Company expects to collect in exchange for the Company’s products is an estimate and may be fixed or variable. Consideration includes reimbursement from both patients and insurance carriers, adjusted for variable consideration related to disallowed cases, percent of patient responsibility collected, refunds and reserves, and is estimated using the expected value method. For insurance carriers and product types with similar reimbursement characteristics, the Company uses a portfolio of relevant historical data to estimate variable consideration and total collections for the Company’s products. The Company constrains the estimated variable consideration when it determines it is probable that a significant reversal in the amount of cumulative revenue recognized may occur in future periods. The consideration expected from laboratory partners usually includes a fixed amount, but it can be variable depending on the volume of tests performed, and the Company determines the variable consideration using the expected value approach. For laboratory partners and patients, the Company allocates the total consideration to a single performance obligation, which is the delivery of the test results to the customers. When assessing the total consideration expected to be received from insurance carriers and patients, a certain percentage of revenues is further constrained for estimated refunds. The Company enters into contracts with insurance carriers primarily with payment terms related to tests provided to patients who have health insurance coverage. Insurance carriers are considered third-party payers on behalf of the patients, and the patients are considered the customers who receive genetic test services. Tests may be billed to insurance carriers, patients, or a combination of insurance carriers and patients. Further, the Company sells tests to a number of domestic and international laboratory partners and identifies the laboratory partners as customers, provided that there is a test services agreement between the two parties. The Company generally bills an insurance carrier, a laboratory partner or a patient upon delivery of test results. The Company also bills patients directly for out-of-pocket costs involving co-pays and deductibles that they are responsible for. The Company may or may not get reimbursed for the full amount billed. Further, the Company may not get reimbursed at all for tests performed if such tests are not covered under the insurance carrier’s reimbursement policies or the Company is not a qualified provider to the insurance carrier, or if the tests were not previously authorized. Product revenue is recognized in an amount equal to the total consideration (as described above) expected to be received at a point in time when the test results are delivered. Approximately 90% of cash collections attributable to such product revenue occurs within nine months, with the remaining collections generally taking an additional six months. During this time, management routinely reassesses its estimates of actual to expected cash collections, which are based on historical collection rates and adjusted for current information and trends. To the extent cash collections for tests delivered in prior periods are trending higher than expectations, the Company will increase revenue recognized when sufficient evidence is obtained to conclude the additional revenue will not result in a significant reversal of revenue in a future period. If cash collections for tests delivered in prior periods are trending below expectations, the Company will reduce revenue to the amount expected to be collected based on the latest information and expectations. Increases or decreases to the amount of cash expected to be collected for tests delivered in prior periods are recognized in product revenue with a corresponding impact to accounts receivable during the period such determination is made. During the three months ended June 30, 2025 and 2024, the Company increased revenue by a net of $45.3 million and $39.9 million, respectively, for changes in estimate that increased revenue for tests delivered in prior periods that were fully collected, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by $0.33 and $0.32 for the three months ended June 30, 2025 and 2024, respectively. During the six months ended June 30, 2025 and 2024, the Company increased revenue by a net of $79.6 million and $73.7 million, respectively, for changes in estimate that increased revenue for tests delivered in prior periods that were fully collected, which increased revenue and decreased net loss by a corresponding amount and decreased loss per share by $0.59 and $0.60 for the six months ended June 30, 2025 and 2024, respectively. Initially, product revenue and accounts receivable are constrained by estimated future refunds to insurance carriers. This allowance is used in later quarters to offset actual refunds. During the three months ended June 30, 2025 and 2024, this allowance decreased revenue and increased net loss by $3.1 million and $3.4 million, respectively, which increased loss per share by $0.02 and $0.03, respectively. During the six months ended June 30, 2025 and 2024, this allowance decreased revenue and increased net loss by $5.8 million and $5.2 million, respectively, which increased loss per share by $0.04 for both periods. Reserves for insurance carrier refunds due to overpayments are held as accrued liabilities until they are either paid or until it is determined that no refund will be made. When refunds are deemed unnecessary, the liability is reduced, increasing revenue. During the three months ended June 30, 2025 and 2024, these adjustments increased revenue and decreased net loss by $0.4 million and $0.6 million, respectively, decreasing loss per share by less than $0.01 and $0.01, respectively. During the six months ended June 30, 2025 and 2024, these adjustments increased revenue and decreased net loss by $0.9 million and $4.1 million, respectively, decreasing loss per share by $0.01 and $0.03, respectively. ​ Licensing and Other Revenues ​ The Company recognizes licensing revenues from its cloud-based distribution service offering, Constellation, by granting licenses to its licensees to use certain of the Company’s proprietary intellectual properties and cloud-based software and in vitro diagnostic (“IVD”) kits. The Company also recognizes revenues from its strategic collaboration agreements, such as those with BGI Genomics Co., Ltd. (“BGI Genomics”) and Foundation Medicine, Inc. (“Foundation Medicine”). The Company recognizes licensing and other revenues through agreements with pharmaceutical companies in support of potential clinical trials managed by the pharmaceutical companies. Constellation The laboratory partners with whom the Company enters into a licensing arrangement represent the licensees and are identified as customers. The licensees do not have the right to possess the Company’s software, but rather receive services through the cloud software. These arrangements often include: (i) the delivery of the services through the cloud software, (ii) the necessary support and training, and (iii) the IVD kits to be consumed as tests are processed. The Company does not consider the software as a service, the support or the training as being distinct in the context of such arrangements, and therefore, they are combined as a single performance obligation. The software, support and training are delivered simultaneously to the licensees over the term of the arrangement. The Company bills the majority of licensees, who process the tests in their laboratories, a fixed price for each test processed. Licensing revenues are recognized as the performance obligations are satisfied (i.e., upon the delivery of each test) and reported in licensing and other revenues in the Company’s statements of operations and comprehensive loss. BGI Genomics In February 2019, the Company entered into a License Agreement (the “BGI Genomics Agreement”) with BGI Genomics to develop, manufacture, and commercialize next generation sequencing-based genetic testing assays for clinical and commercial use. The BGI Genomics Agreement has a term of ten years and expires in February 2029. Pursuant to the BGI Genomics Agreement, the Company licensed its intellectual property to and provided development services for BGI Genomics. Following completion of development services, the Company began providing assay interpretation services over the term of the agreement. According to the BGI Genomics Agreement, the Company is entitled to a total of $50.0 million, comprised of upfront technology license fees, prepaid royalties relating to future sales of licensed products and performance of assay interpretation services, and milestone payments. Due to uncertainties in achieving certain milestones, $6.0 million of the $50.0 million was constrained. A net of $44.0 million has been collected by the Company in cash, which includes $20.0 million in prepaid royalties. The Company concluded that the license is not a distinct performance obligation as it does not have a stand-alone value to BGI Genomics apart from the related development services. Therefore, license and related development services for each of the non-invasive prenatal tests (“NIPTs”) and Oncology products, representing two separate performance obligations, to which $24.0 million of transaction consideration was allocated. This performance obligation was fully satisfied in March 2023 and no further related amounts will be recognized as revenue. As of December 31, 2023, the Company's performance obligation to provide ongoing NIPT assay interpretation services was removed. Therefore, the Company now has a single remaining performance obligation related to Oncology assay interpretation services, to which $20.0 million of transaction consideration was allocated and prepaid by BGI Genomics. During the six months ended June 30, 2025, the Company recognized $0.3 million related to oncology assay interpretation services, which was recognized against deferred royalties. During the six months ended June 30, 2024, the Company recognized an additional $0.1 million related to oncology assay interpretation services, which was recognized against deferred royalties. The Company has $17.0 million and $17.3 million in deferred revenue as of June 30, 2025 and December 31, 2024, respectively.
