Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying Condensed Consolidated Financial Statements include Impinj, Inc. and its wholly owned subsidiaries. We have eliminated intercompany balances and transactions in consolidation. We have prepared these Condensed Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC, regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2025 included in Impinj, Inc.’s Annual Report on Form 10-K, which was filed with the SEC on February 9, 2026. The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, comprising normal recurring adjustments, necessary to state fairly our financial position, results of operations and our cash flows for the periods presented. Interim results are not necessarily indicative of the results for a full year or for any other future period.
Use of Estimates | Use of Estimates Preparing financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the financial statements, as well as the reported revenue and expenses during the periods presented. We evaluate our estimates on an ongoing basis, including those related to revenue recognition, sales incentives, the fair value of assets acquired, liabilities assumed, contingent consideration in business combinations, inventory excess and obsolescence and income taxes. To the extent there are material differences between our estimates, judgments or assumptions and our actual results, our financial statements will be affected.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards In December 2023, the FASB released Accounting Standard Update, or ASU, 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which amends income tax disclosure requirements to enhance the transparency and decision usefulness for users of the financial statements. The standard is effective for fiscal years beginning after December 31, 2024. We adopted ASU 2023-09 on January 1, 2025 using the retrospective transition method. We have adjusted the financial statements to reflect the application of the new accounting guidance for all periods presented (See Note 7 of our Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2025). In November 2024, the FASB released ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20), which improves the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20, Debt - Debt with Conversion and Other Options. The standard is effective for fiscal years beginning after December 31, 2025, and early adoption is permitted. We early adopted ASU 2024-04 on January 1, 2025, using the prospective transition approach. As a result of our adoption, we accounted for the exchange of the 2021 Notes in September 2025 described below, as an induced conversion. See Note 7 for additional details of this exchange transaction.
Recently Issued Accounting Standards Not Yet Adopted | Recently Issued Accounting Standards Not Yet Adopted In November 2024, the FASB released ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which amends disclosure requirements related to the disaggregation of income statement expenses in the notes to financial statements. In January 2025, the FASB released ASU 2025-01, clarifying that the standard is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. We are currently evaluating any impact of this standard on our financial statement disclosures.
