Principles of Consolidation The condensed consolidated financial statements include the accounts of Astera Labs, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2026 compared with the significant accounting policies described in its Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 20, 2026. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make 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 revenue and expenses during the reporting periods. The Company’s significant estimates include, but are not limited to, revenue recognition, the valuation of acquired intangible assets, the valuation and realizability of deferred tax assets, reserves for uncertain tax positions, useful life of production equipment, the valuation of warrants, and the valuation and assumptions underlying stock-based compensation. By their nature, estimates are subject to an inherent degree of uncertainty and actual results could differ from those estimates. The Company assessed certain accounting matters and estimates that generally require consideration of forecasted information available to the Company. Management is not aware of any specific event or circumstance that would require an update to estimates or judgments or a revision to the carrying value of assets or liabilities. These estimates and judgments may change as new events occur and additional information is obtained, which may result in changes being recognized in the Company’s consolidated financial statements in future periods, and actual results could differ from these estimates. Reclassifications Certain prior period balances were reclassified to conform to the current period’s presentation. None of these reclassifications had an impact on reported net income, balance sheets, or cash flows for any of the periods presented. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosure (“ASU 2024-03”), and in January 2025, the FASB issued Accounting Standards Update No. 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosure (Subtopic 220-40): Clarifying the Effective Date (“ASU 2025-01”). ASU 2024-03 requires additional disclosures of the nature of expenses included in the income statement and disclosures about specific expense categories included in the expense captions presented in the statements of operations. ASU 2024-03, as clarified by ASU 2025-01, is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. Both early adoption and retrospective application are permitted. The Company is currently evaluating the impact that the adoption of these new standards will have on its consolidated financial statements and related disclosures. In May 2025, the FASB issued Accounting Standards Update No. 2025-04, Compensation-Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”). ASU 2025-04 reduces diversity in practice and improves the decision usefulness and operability of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. The ASU is effective for annual reporting periods beginning after December 15, 2026 with updates to be applied on a retrospective or modified retrospective basis. Early adoption is permitted. The Company does not expect a material impact from the adoption of this ASU on its consolidated financial statements and related disclosures. In September 2025, the FASB issued Accounting Standards Update No. 2025-06, Intangibles - Goodwill and Other -Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 removes all references to project stages throughout Subtopic 350-40 and clarifies the threshold that the entities must meet to begin capitalizing costs. The ASU is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the impact that this new standard will have on the Company’s consolidated financial statements and related disclosures.
