Summary of Significant Accounting Policies (Policies) | 9 Months Ended
--- | ---
Sep. 30, 2025
Accounting Policies [Abstract] |
Basis of Presentation | The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Prior to April 2024, the financial statements also included the Company’s wholly owned subsidiary SeqIndia Labs Private Limited which had immaterial activities and was not material to these financial statements and was divested in April 2024. All intercompany transactions and balances have been eliminated upon consolidation. The unaudited interim financial statements should be read in conjunction with the audited financial statements and the related notes thereto as of and for the year ended December 31, 2024, included in the Company's prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on November 6, 2025 (the “Final Prospectus”). For a summary of the Company’s significant accounting policies refer to “Note 2. Summary of Significant Accounting Policies” in the notes to the financial statements as of and for the year ended December 31, 2024 included in the Final Prospectus. There have been no significant changes to these policies during the nine months ended September 30, 2025.
Consolidation | All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates | The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On a regular basis, management evaluates estimates, including, but not limited to: the fair value of common stock, stock-based compensation, deferred tax assets and liabilities, useful lives of long-lived assets, the incremental borrowing rate applied to operating and finance leases, determination of revenue recognition and accounts receivable, the valuation of warrants for common stock and warrants for redeemable convertible preferred stock, and valuation of debt and convertible notes. These estimates are inherently subject to judgment and actual results could differ from those estimates.
Revenue | The Company recognizes revenue upon transfer of control of promised goods and services in an amount that reflects the consideration it expects to be entitled to receive in exchange for those goods and services. Under ASC 606—Revenue from Contracts with Customers (ASC 606), the Company applies the following five-step approach: •Identify the contract with a customer •Identify the performance obligations in the contract •Determine the transaction price •Allocate the transaction price to the performance obligations in the contract •Recognize revenue when, or as, a performance obligation is satisfied The Company generates revenue primarily from prenatal and oncology testing services, which are referred to as testing services or test results. The Company considers the patient as its customer, that requests a test service through their physician. Test results are the single performance obligation being provided to customers. Testing service revenue is recognized at a point in time when test results are delivered to the ordering physician. The Company generally bills an insurance carrier, Medicaid, Medicare, or a patient or a combination of both upon delivery of test results. The Company enters into contracts with third-party payors, including insurance carriers and Medicaid, to set the pricing for tests provided to patients. Due to the nature of these third-party payor contract arrangements, the total consideration the Company expects to collect for test results is variable as they are dependent on the terms negotiated with the third-party payor. The predominance of the Company’s revenue is derived from payments by third-party insurance carriers. The Company uses the expected value method of estimating variable consideration. The total consideration the Company expects to collect in exchange for the Company’s products is an estimate and is largely variable in nature. Consideration includes reimbursement from both patients and third-party payors. The Company establishes variable consideration by considering historical payment trends for tests delivered, test reimbursement disallowances, and contractual arrangements in place, among other factors, which is adjusted for current expectations. Current expectations of cash collections factor in changes in reimbursement rate trends, historical events not expected to recur, and future known changes such as anticipated contractual pricing changes or changes to insurance coverage. The Company also considers hindsight, where applicable, in estimates established for variable consideration and updates those estimates when actual experience supports doing so. In establishing variable consideration, the Company considers payors with similar reimbursement characteristics together. The Company monitors the cash collections against the estimated variable consideration over the expected cash collection period and any difference is recognized as an adjustment to estimated revenues after such estimated cash collection period has closed. In January 2023, the Company entered a partnership with Johnson & Johnson under which the Company is licensing the Company’s proprietary knowledge, performing clinical trial support services including developing a clinical study assay, and other testing services to support a clinical trial for the counterparty. The Company concluded that the agreement with Johnson & Johnson was within the scope of ASC 606 because the counterparty in the agreement meets the definition of a customer. The Company evaluated the terms of the agreement for revenue recognition, including whether the services are capable of being distinct and considered distinct within the context of the contract. The Company concluded that the licensing of the know how is not distinct from the other promises within the agreement and, as a result, was treated as a single performance obligation. Under this contract the Company receives payments upon the achievement of milestones, including (i) receipt of approval of the trial, which was achieved in 2023, (ii) various patient enrollment milestones, and (iii) subsequent full trial completion, as well as reimbursement for testing services. In making assessment of whether variable consideration should be included in the transaction price, the Company considers the degree of complexity and uncertainty associated with each milestone and related testing services, and whether achievement of the milestones and testing services are dependent on parties other than the Company. In July 2025, the Company entered into a partnership with Johnson & Johnson for the development and commercialization of a companion diagnostic (CDx), intended for use with a new drug candidate of Johnson & Johnson. The Company is providing services related to regulatory filings to support companion diagnostic submissions for the Company’s assay. The development and regulatory support services represent a single performance obligation as the Company performs a significant integration service, such as analytical validation and regulatory submissions. The individual promises are not separately identifiable from other promises in the contract, and therefore, not distinct. The Company generates revenue from achievement of milestones, including (i) various CDx development milestones, (ii) FDA regulatory submission and pre-approval, and (iii) CDx approval by FDA. For the companion diagnostic development and regulatory approval performed, the Company is compensated through a combination of an upfront fee and performance-based, non-refundable regulatory and development milestones. The transaction price represents variable consideration and the Company uses the most likely amount to estimate variable consideration. Application of the constraint for variable consideration to milestone payments is an area that requires significant judgment. The Company evaluates factors such as the scientific, clinical, regulatory, and other risks that must be managed to achieve the respective milestone and the level of effort and investment required to achieve the respective milestone. In making this assessment, the Company considers its historical experience with similar milestones, the degree of complexity and uncertainty associated with each milestone, and whether the achievement of the milestone is dependent on parties other than the Company. The constraint for variable consideration is applied to the contract price such that it is probable a significant cumulative reversal of revenue will not occur when the uncertainty associated with the contingency is resolved. Application of the constraint for variable consideration is assessed and updated at each reporting period as a revision to the estimated transaction price. The Company recognizes revenue for the single performance obligation for the J&J partnership agreements over the period the services are provided. Specifically, the Company recognizes revenue using an input method to measure progress, utilizing costs incurred to-date relative to the total expected costs as a measure of progress. The Company assesses the changes to the total expected cost estimates in determining the revenue recognition for each reporting period. The Company applies the practical expedient not to disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. As of September 30, 2025, the Company’s remaining performance obligations beyond one year were approximately $4.7 million. Disaggregation of revenue The following table presents disaggregation of revenue by Prenatal, Oncology and Clinical trial support and other services for the three and nine months ended September 30, 2025 and 2024 (in thousands):
| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Prenatal | $ | 74,071 |  |  | $ | 36,601 |  |  | $ | 191,001 |  |  | $ | 102,680 |
Oncology | 8,691 |  |  | 1,138 |  |  | 15,814 |  |  | 1,851 |
Clinical trial support and other services | 761 |  |  | 680 |  |  | 2,244 |  |  | 2,974 |
Total revenues | $ | 83,523 |  |  | $ | 38,419 |  |  | $ | 209,059 |  |  | $ | 107,505 |
Substantially all revenues recognized for the three and nine months ended September 30, 2025 and 2024 were generated in the United States. Deferred revenue Deferred revenue, which is a contract liability, consists of billings or cash received for services in advance of revenue recognition and is recognized as revenue when all the Company’s revenue recognition criteria are met. As of September 30, 2025 and December 31, 2024, the deferred revenue balance was $2.7 million and $2.8 million, respectively, all of which is considered short-term. For the three months ended September 30, 2025 and 2024 and nine months ended September 30, 2025 and 2024, revenue recognized from deferred revenue at the beginning of the period was $0.6 million, $0.7 million, $2.1 million, and $3.0 million, respectively.
Deferred Offering Costs | Deferred offering costs, consisting of legal, accounting, and other fees and costs relating to the Company’s initial public offering (IPO) are capitalized within other non-current assets on the balance sheets. The deferred offering costs will be offset against the proceeds received by the Company upon the closing of the IPO.
Segment Information | Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and assess performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information presented on a company-wide basis to make operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it is managed as one operating segment and one reportable segment. Key areas of focus for the CODM when making decisions on the allocations of resources is cash used in operations as well as revenue, gross margin and net income (loss); this information is used by the CODM and compared to budgeted amounts in order for the CODM to make decisions on how resources should be allocated across the organization. The Company’s segment measure of profitability is net income (loss). Segment revenues are derived from prenatal and oncology testing results, leveraging the Company’s diagnostic technology platform, which are delivered to patients, who are the Company’s customer. The Company’s customers are predominantly located in the United States. Substantially all of the Company’s long-lived assets are located in the United States. The Company’s technology platform is applied similarly in both the prenatal and oncology settings. The financial statements provide the CODM with a view of the Company’s financial condition as it pertains to the Company’s assets, liabilities and expenses. Significant expense categories align with the expense categories and amounts presented on the statements of operations.
Recently Issued Accounting Pronouncements not yet Adopted | In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which expands income tax disclosure requirements to include additional information related to the rate reconciliation of effective tax rates to statutory rates, as well as additional disaggregation of taxes paid. This ASU also removed disclosure related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. This ASU may be applied prospectively or retrospectively, and early adoption is permitted. The Company is currently evaluating this ASU to determine the impact it may have on its financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-04, Debt – Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. This ASU clarifies guidance on the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion or extinguishment. This guidance is effective for the Company beginning on January 1, 2026, and early adoption is permitted, although the Company does not plan to early adopt. The Company is currently evaluating the impact of the adoption of this standard on the Company’s financial statement disclosures. In November 2024 and January 2025, the FASB issued ASU 2024-03 and ASU 2025-01, respectively, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disclosure in the notes to the financial statements of specified information about an entity’s certain costs and expenses. The amendments to the standards are effective for the Company’s fiscal year beginning January 1, 2027 and interim periods beginning January 1, 2028. Early adoption is permitted. The amendments should be applied either prospectively to the financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating this ASU to determine the impact it may have on its financial statements and related disclosures. In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides for a practical expedient to estimate credit losses related to accounts receivable and contract assets from revenue contracts accounted for in accordance with ASC 606 using information as of the balance sheet date. This ASU is effective for the Company’s fiscal year beginning January 1, 2026 and early adoption is permitted. The Company is currently evaluating this ASU to determine the impact it may have on its financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and expands the existing guidance on capitalizing implementation costs for cloud computing arrangements that are service contracts. The new guidance is effective for public business entities for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating this ASU to determine the impact it may have on its financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-07, Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract, which amends the guidance under ASC Topic 815 (Derivatives and Hedging) and ASC Topic 606 (Revenue from Contracts with Customers). The ASU (i) refines the scope for derivative accounting to exclude certain non-exchange-traded contracts whose underlyings are based on the operations or activities specific to one of the parties to the contract, and (ii) provides clarification on how to account for share-based noncash consideration from customers (such as equity instruments, warrants, or shares) received in exchange for the transfer of goods or services under a revenue contract. The new guidance is effective for public business entities for fiscal years beginning after December 15, 2026, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating this ASU to determine the impact it may have on its financial statements and related disclosures.
