Summary of Significant Accounting Policies

Note 1. Summary of Significant Accounting Policies

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 (“GAAP”), and applicable rules and regulations of the Securities and Exchange Commission (“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, 2024 included in Impinj, Inc.’s Annual Report on Form 10-K, which was filed with the SEC on February 10, 2025.

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

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 actual results, our financial statements will be affected.

Licensing of Intellectual Property

On March 13, 2024, we and NXP Semiconductors N.V. (“NXP”) entered into a Settlement and Patent Cross-License Agreement (the “Settlement Agreement”). Under the Settlement Agreement, NXP made a one-time payment of $45 million and agreed to make annual license fee payments on April 1 of each year, starting on April 1, 2024, until the termination of the Settlement Agreement. During first-quarter 2024, we recorded the $45 million payment in income from settlement of litigation in the condensed consolidated statements of operations. We will recognize the license fee, which relates to annual usage of the license from April 1 to March 31 of each applicable year, as revenue in the second quarter of each year until the Settlement Agreement terminates. We recognized the license fee for the first annual usage period in second-quarter 2024. See Note 6 Commitments and Contingencies for additional details of the Settlement Agreement with NXP.
