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.

Recently Adopted Accounting Standards

In November 2024, the FASB released Accounting Standard Update (“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 Debt for additional details of this exchange transaction.

Recently Issued Accounting Standards Not Yet Adopted

In December 2023, the FASB released 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 are currently evaluating impact of this standard, if any, on our financial statement disclosures.

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.

Note 2. Fair Value Measurements

Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

•

Level 1 — Quoted prices in active markets for identical assets or liabilities.

•

Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities.

•

Level 3 — Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require.

We did not have any financial assets or liabilities in Level 3 as of September 30, 2025 or December 31, 2024.

We applied the following methods and assumptions in estimating our fair value measurements:

Cash Equivalents — Cash equivalents comprise highly liquid investments, including money market funds with original maturities of less than three months at the acquisition date. We record the fair value measurement of these assets based on quoted market prices in active markets.

Investments — Our investments comprise fixed income securities, which include U.S. government agency securities, corporate notes and bonds, commercial paper and treasury bills. The fair value measurement of these assets is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Long-term Debt — See Note 7 for the carrying amount and estimated fair value of the 2021 Notes and 2025 Notes.

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, as of the dates presented (in thousands):

We expect short-term investments to mature within 1 year and long-term investments within 1 to 3 years of the reporting date.

Investments

The following tables present the cost or amortized cost, gross unrealized gains, gross unrealized losses and total estimated fair value of our financial assets as of the dates presented (in thousands):

Marketable securities in a continuous loss position for less than 12 months had an estimated fair value of $47.9 million and $0.1 million in unrealized losses as of September 30, 2025, and an estimated fair value of $142.8 million and $0.6 million in unrealized losses as of December 31, 2024. Marketable securities in a continuous loss position for greater than 12 months had an estimated fair value of $45.8 million and immaterial losses as of September 30, 2025. There wereno marketable securities in a continuous loss position for greater than 12 months as of December 31, 2024.

Note 6. Commitments and Contingencies

For information on our commitments and contingencies, see Part II, Item 8 (Financial Statements and Supplementary Data, Note 12, Commitments and Contingencies) of our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes to our commitments and contingencies as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024, except for “Obligations with Third Parties” and “Litigation” as discussed below.

Obligations with Third Parties

We manufacture products with third-party manufacturers. We are committed to purchase$24.6 million of inventory as of September 30, 2025.

Litigation

From time to time, we are subject to various legal proceedings or claims that arise in the ordinary course of business. We accrue a liability when management believes that it is both probable that we have incurred a liability and we can reasonably estimate the amount of loss. As of September 30, 2025 and December 31, 2024, we didnot have accrued contingency liabilities. The following is a description of our significant legal proceedings.

Patent Infringement Claims and Counterclaims

Impinj Patent Infringement Claims Against NXP

From 2019 to 2023, we engaged in active patent litigation against our primary endpoint IC competitor, NXP Semiconductors N.V., or NXP. During this time, we filed three patent infringement lawsuits against subsidiaries of NXP in federal courts in California and Texas. Our complaints alleged that certain NXP endpoint ICs infringed a number of our U.S. patents. In response, NXP filed a suit against us in federal court in Delaware, later transferred to Washington, countersued us in Texas, and filed three lawsuits against our subsidiary in China. NXP’s complaints alleged that certain of our endpoint ICs infringed a number of their own U.S. or Chinese patents or U.S. patents that they exclusively licensed from a third-party to assert against us.

Through 2023, we prevailed in these lawsuits. In three U.S. trials held in 2023, juries in California and Texas returned verdicts that NXP endpoint ICs infringed five of our patents that made it to trial, and juries in Washington and Texas ruled that we did not infringe any of the three patents NXP accused us in court of infringing. Also in 2023, NXP withdrew all three cases it filed against us in China.

On March 13, 2024, while additional trials were pending in China and Texas, and post-trial motions and appeals were pending in China and the U.S., we and NXP entered into the Settlement Agreement. Under the agreement we and NXP agreed to terminate and withdraw all pending proceedings and release one another for all patent infringement claims preceding March 31, 2024 and grant to each other non-exclusive, worldwide patent licenses to make, have made, import, use, offer for sale and sell their respective products and services, subject to the terms of the agreement. The Settlement Agreement will remain in force until all the valid claims of a specified set of Impinj patents, or the Indicator Patents, expire in about ten years. Either party can terminate the Settlement Agreement if the other party materially breaches the terms of the Agreement and NXP can terminate the Settlement Agreement if it successfully designs out all valid claims of the Indicator Patents.

Under the Settlement Agreement, NXP paid us a one-time amount of $45.0 million and agreed to make annual license fee payments, if the specified set of Indicator Patents are still in use, on April 1 of each year, effective April 1, 2024. The annual license fee will increase by a fixed percentage each year after 2024 for the remaining term of the Settlement Agreement. We have no obligation to pay NXP under the Settlement Agreement.

We allocated the consideration from the Settlement Agreement to the components of the Settlement Agreement. We recorded the $45.0 million payment in income from settlement of litigation in the condensed consolidated statements of operations in first-quarter 2024, upon receipt, and recognized the first and second annual license fees of $15.0 million and $16.0 million in revenue in second-quarter 2024 and 2025, respectively. Licensing of our intellectual property is part of our ongoing operations and therefore, 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.

Note 7. Long-term debt

Convertible Senior Notes

In November 2021, we issued $287.5 million aggregate principal amount of convertible promissory notes due May 15, 2027 (the “2021 Notes”) and in September 2025, we issued $190.0 million aggregate principal amount of convertible promissory notes due September 15, 2029 (the “2025 Notes” and collectively, the “Notes”).

The following table presents the outstanding principal amount and carrying value of the Notes as of the dates indicated (in thousands):

Further details of the Notes are as follows:

The Notes are our senior unsecured obligations, do not contain any financial covenants and are governed by indentures (the “Indentures”). The 2025 Notes do not bear regular interest and the principal amount of the 2025 Notes does not accrete. The total net proceeds from the 2021 Notes and the 2025 Notes, after deducting initial debt issuance costs, fees and expenses, were $278.4 million and $183.6 million, respectively. We used approximately $183.6 million of the 2021 Notes net proceeds, excluding accrued interest, to repurchase approximately $76.4 million aggregate principal amount of convertible notes due 2026 (the “2019 Notes”)through individual privately negotiated transactions concurrent with us offering the 2021 Notes. We used approximately $17.6 million, excluding accrued interest, to repurchase the remaining $9.9 million aggregate principal amount of the 2019 Notes in June 2022. Weused the remainder of the net proceeds from the 2021 Notes for general corporate purposes. We used the 2025 Notes net proceeds, and cash on hand to exchange $190.0 million aggregate principal amount of the 2021 Notes for approximately $190.0 million in cash, representing the principal amount exchanged, and approximately 811,000 shares of our common stock, representing the exchange value in excess thereof, and also paid accrued and unpaid interest thereon, in privately negotiated transactions concurrently with the 2025 Notes offering.

Terms of the Notes

The holders of each series of Notes may convert their respective Notes at their option at any time prior to the close of business on the business day immediately preceding the respective conversion dates under the following circumstances:

•

during any fiscal quarter commencing after the fiscal quarter ending on March 31, 2022 (for the 2021 Notes) and the fiscal quarter ending on December 31, 2025 (for the 2025 Notes) (and only during such fiscal quarter), if the last reported sale price of our common stock, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•

during thefive business day period after anyfive consecutive trading day period in which the trading price per $1,000 principal amount of the applicable series of Notes for each trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for such series of Notes on each such trading day;

•

prior to the close of business on the second scheduled trading day immediately preceding the redemption date if we call the applicable series of Notes for redemption; or

•

upon the occurrence of specified corporate events, as described in the Indenture governing each series of Notes.

Regardless of the foregoing circumstances, holders may convert all or any portion of the 2021 Notes, in increments of $1,000 principal amount, on or after February 15, 2027, and may convert all or any portion of the 2025 Notes, in increments of $1,000 principal amount, on or after June 15, 2029, until the close of business on the second scheduled trading day immediately preceding the maturity date for the applicable series of Notes.

We may redeem all or any portion of the 2021 Notes for cash, at our option, on or after November 20, 2024, and all or any portion of the 2025 Notes for cash, at our option, on or after March 20, 2028, if the last reported sale price of our common stock has been at least 130% of the conversion pricefor the applicable series of Notes for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date for such Notes.

Holders who convert their Notes in connection with certain corporate events that constitute a make-whole fundamental change (as defined in the Indenture governing each series of Notes) are, under certain circumstances, entitled to an increase in the conversion rate for such Notes. Additionally in the event of a corporate event constituting a fundamental change (as defined in the Indenture governing each series of Notes), holders of the Notes may require us to repurchase all or a portion of their Notes of such series at a repurchase price equal to 100% of the principal amount of the Notes of such series being repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.

Our common stock exceeded 130% of the conversion price of the 2021 Notes for more than 20 trading days during the 30 consec utive trading days ended September 30, 2025. Accordingly, the 2021 Notes are convertible at the option of the holders as of September 30, 2025 and therefore, have remained classified as current portion of long-term debt on the condensed consolidated balance sheet as of September 30, 2025. The “if-converted value” exceeded the principal amounts by $61.2 million based on the closing price of our common stock of $180.75 as of September 30, 2025.

Accounting for the Notes

The 2025 Notes are accounted for as a single liability measured at its amortized cost. We presented the 2025 Notes total issuance costs of$6.3 million as a direct deduction from the face amount of the 2025 Notes. We amortize the issuance costs to interest expense over the respective term of the 2025 Notes using the effective interest rate method.

Interest expense related to the Notes was as follows (in thousands):

Accrued interest related to the 2021 Notes as of September 30, 2025 and December 31, 2024 was $0.4 millionand $0.4 million, respectively. There is no accrued interest for the 2025 Notes. We record accrued interest in accrued liabilities in our consolidated balance sheet.

We estimate the fair value of the 2021 Notes to be$162.9 million and $408.7 million as of September 30, 2025 and December 31, 2024, respectively, which we determined through consideration of quoted market prices. We estimate the fair value of the 2025 Notes to be$194.6 million as of September 30, 2025, which we determined through consideration of quoted market prices. The fair value for the Notes is classified as Level 2, as defined in Note 2.

Capped Call Transactions

In connection with issuing the 2019 Notes and the 2025 Notes, we entered into privately negotiated capped call transactions with certain financial counterparties. The capped call transactions are generally expected to reduce the potential dilution to our common stock upon any conversion of the 2019 Notes or the 2025 Notes, and/or offset any cash payments we would be required to make in excess of the principal amount of converted 2019 Notes or 2025 Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. If, however, the market price per share of our common stock exceeds the cap price of the respective capped call transactions, then our stock would experience some dilution and/or such capped call transactions would not fully offset the potential cash payments, in each case, to the extent the then-market price per share of our common stock exceeds the cap price.

The capped call transactions entered into in connection with the 2019 Notes, remains outstanding even though we have repurchased the 2019 Notes, to reduce the potential dilution of the remaining 2021 Notes. The initial cap price of these capped call transactions is $54.20 per share, subject to certain adjustments under the terms of these capped call transactions. These capped call transactions expire over 40 consecutive scheduled trading days ending on December 11, 2026.

The initial cap price of the capped call transactions, entered into in connection with the 2025 Notes, is $340.32 per share, subject to certain adjustments under the terms of these capped call tran sactions. These capped call transactions expire on September 15, 2029. The cost of $11.2 million incurred in connection with the 2025 capped call was recorded as a reduction to additional paid-in capital.

The capped call transactions are separate transactions, and not part of the terms of the 2019 Notes or the 2025 Notes. These transactions meet the criteria for classification in equity, are not accounted for as derivatives and are not remeasured each reporting period.

Partial Exchange of the 2021 Notes

In September 2025, we entered into privately-negotiated exchanges with certain holders of our outstanding 2021 Convertible Notes with respect to the exchange of $190.0 million principal amount of the 2021 Convertible Notes (the “2021 Note Exchange”). We accounted for the 2021 Note Exchange transaction as an induced conversion in accordance with Accounting Standards Codification 470-20, Debt with Conversion and Other Options (ASC 470-20), as amended for ASU 2024-04, which we early adopted on January 1, 2025, using the prospective transition approach. In connection with the induced conversion, we paid approximately $190.0 million in cash, representing the principal amount exchanged, issued approximately 811,000 sharesof our common stock, representing the exchange value in excess thereof, and also paid accrued and unpaid interest thereon. As a result of the induced conversion, we recorded $15.0 million in induced conversion expense which is included in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2025. We did not receive any cash proceeds from the issuance of the shares of common stock but recognized additional paid-in-capital of $13.1 million representing the induced conversion expense, net of approximately $2.0 million of unamortized debt issuance costs related to the converted 2021 Notes.

Note 8. Net Earnings (Loss) Per Share

For the periods presented, the following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net earnings (loss) per share (in thousands, except per share amounts):

Basic net earnings (loss) per share is calculated using our net income and our weighted average outstanding common shares.

Diluted net earnings (loss) per share is calculated using our net income (loss) attributable to common stockholders with interest charges applicable to our convertible debt added back under the if converted method, if dilutive, and our weighted average outstanding common shares including the dilutive effect of stock awards and employee stock purchase plan shares as determined under the treasury stock method and of our convertible notes using the if converted method, if dilutive. In periods when we recognize a net loss, we exclude the impact of outstanding stock awards and the potential share settlement impact related to our convertible notes from the diluted loss per share calculation as their inclusion would have an antidilutive effect.

The following table presents the outstanding shares of our common stock equivalents excluded from the computation of diluted net earnings (loss) per share as of the dates presented because their effect would have been antidilutive (in thousands):

Note 9. Segment Information

We haveone reportable and operating segment: Developing and selling our RAIN products and services. We identified our operating segment based on how our chief operating decision-maker manages our business, makes operating decisions and evaluates our operating performance. Our chief executive officer acts as the chief operating decision-maker and reviews financial and operational information on an entity-wide basis. Accordingly, we have determined we have a single reportable and operating segment.

Our chief executive officer reviews information about our revenue categories: Endpoint ICs, including licensing revenue, and systems, defined as reader ICs, readers, gateways, test and measurement solutions and software and services. The following table presents our revenue categories for the indicated periods (in thousands):

Significant Segment Expenses

We adopted ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures on January 1, 2024. As our CODM manages operations on a consolidated basis, consolidated net income as reported in our Statement of Operations is the GAAP measure that is used to make operating decisions and evaluate operating performance. The significant expense categories which are used to manage operations are those reflected in our condensed consolidated Statement of Operations.

Note 10. Deferred Revenue

Deferred revenue, comprising individually immaterial amounts for extended warranty, enhanced product maintenance and advance payments on nonrecurring engineering (“NRE”) services contracts, represents contracted revenue that has not yet been recognized. We recognized $1.4 millionof revenue related to amounts included in deferred revenue as of December 31, 2024 for the nine months ended September 30, 2025. We recognized $1.3 million of revenue related to amounts included in deferred revenue as of December 31, 2023 for the nine months ended September 30, 2024.

The following table presents the changes in deferred revenue for the indicated periods (in thousands):

Note 11. Restructuring

On February 7, 2024, we initiated a strategic restructuring to align financial, business and research and development objectives for long-term growth, including a reduction-in-force affecting approximately 10%of our employees. We incurred restructuring chargesof $1.8 million for employee terminations benefits, including equity modification expense in first-quarter 2024. Restructuring payments were complete in second-quarter 2024.
