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.

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.

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.
