Accounting Policies [Abstract] |
Basis of Accounting and Consolidation | Basis of Accounting and Consolidation The accompanyin g unaudited condensed consolidated financial statements have been prepared by the Company and reflect all adjustments, consisting only of normal recurring adjustments, that are, in the opinion of management, necessary for the fair presentation of its financial position, results of operations, cash flows and stockholders' equity for the interim periods presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information and include the accounts of the Company and its wholly owned subsidiaries. Accordingly, these statements do not include all information and footnotes required by U.S. GAAP for annual consolidated financial statements, and should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended December 31, 2024 included in the Company's final prospectus, dated July 29, 2025, filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (Securities Act), on July 31, 2025 (the Prospectus) in connection with the Company's initial public offering (IPO). The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the operating results expected for the full fiscal year or future operating periods. The condensed consolidated balance sheet as of December 31, 2024 has been derived from the Company’s audited consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. There have been no material changes to the Company’s significant accounting policies described in Note 2 - Summary of Significant Accounting Policies, of the notes to the Company’s audited consolidated financial statements.
Initial Public Offering | Initial Public Offering On July 18, 2025, the Company effected a 1-for-28 reverse stock split (the Stock Split) of the Company’s issued and outstanding shares of common stock and options to purchase common stock. The Stock Split reduced the number of shares of the Company’s issued and outstanding common stock, as well as the numbers of shares underlying the RSUs and the numbers of shares reserved and available for future issuance and underlying outstanding options to purchase common stock. The Stock Split did not affect the par values per share or total authorized common stock. Accordingly, all share and per share amounts for all periods presented in the consolidated financial statements have been adjusted retroactively, where applicable, to reflect the Stock Split. On July 31, 2025, the Company completed its IPO, in which 4,600,000 shares of common stock, par value $0.000001 per share, were issued and sold, inclusive of the exercise in full of the underwriters' option to purchase 600,000 additional shares. The Company received net proceeds of $102.7 million after deducting underwriting discounts and commissions of $7.7 million, but before offering expenses. In connection with the IPO, all shares of redeemable convertible preferred stock then outstanding automatically converted into an aggregate of 12,729,240 shares of common stock, and the Company issued 424,033 shares of common stock upon exercise of warrants and will, at the expiration of the applicable lock-up period, issue 34,254 shares of common stock upon settlement of restricted stock units (RSUs) outstanding for which the performance-based vesting condition was satisfied in connection with the IPO.
Deferred Offering Costs | Deferred Offering Costs Prior to the IPO, deferred offering costs, consisting primarily of accounting, legal and other fees related to the IPO, were capitalized within other current assets in the condensed consolidated balance sheets. Upon consummation of the IPO, $2.8 million of such costs were recorded as a reduction of the proceeds generated from the offering, which was recognized in additional paid-in capital.
Concentration of Risks | Concentration of Risks Financial Instruments Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. The Company maintains its cash and cash equivalent balances in highly rated financial institutions, which at times may exceed federally insured limits or be held in foreign jurisdictions. The Company has not experienced any loss relating to cash and cash equivalents in these accounts and believes no significant concentration risk exists with respect to cash. The Company performs periodic credit evaluations of its customers’ financial conditions and generally does not require collateral. Demand The Company had three customers representing 38%, 26% and 11%, respectively, of total accounts receivable as of September 30, 2025. The Company had three customers representing 61%, 17% and 10%, respectively, of total accounts receivable as of September 30, 2024, one of which was the same customer as of September 30, 2025. There were three end customers representing 41%, 26% and 21%, respectively, of total net sales for the three months ended September 30, 2025. These same three end customers represented 39%, 28%, and 18%, respectively, of total net sales for the nine months ended September 30, 2025. There were three end customers representing 47%, 26%, and 14%, respectively, of total net sales for the three months ended September 30, 2024. These same three end customers represented 37%, 23%, and 20%, respectively, of total net sales for the nine months ended September 30, 2024, two of which were the same customers as of the three and nine months ended September 30, 2025. The loss of one or more of these customers could have a material adverse impact on the Company’s results of operations and financial position. Supply The Company's products depend on a sole supplier of wafers and a limited number of third-party manufacturers. The continued and timely supply of input materials and the availability of manufacturing capacity and packaging and testing services impact the Company's ability to meet customer demand. Supply chain disruptions, shortages of raw materials, and manufacturing limitations could limit the Company's ability to meet customer demand and result in delayed, reduced, or canceled orders. The Company has established relationships with leading suppliers and partners, and believe these relationships increase the resiliency of the Company's supply chain for its customers. From time to time, subject to inventory disruptions, the Company's customers may buy and hold excess inventories. Consequently, the Company may be subject to resulting fluctuations in the demand for its products. End Customer Concentration Although the Company recognizes revenue and directly invoices distributors for sales of its products, the timing and uncertainty of its revenue and cash flows are most impacted by the ultimate end customer. The following is a summary of net sales for the three and nine months ended September 30, 2025 and 2024, based on the country of the corporate headquarters of the ultimate end customer (in thousands):

Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements and disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The update will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. The Company will adopt this amendment effective with its annual financial statements for the year ending December 31, 2025. The Company is currently evaluating the potential impact of adopting this guidance on the notes to the consolidated financial statements.
