Impinj, Inc. Form 8-K AccNo 0001193125-26-388376 (Ex 99.1 dated September 10, 2026): entered privately-negotiated exchange agreements with certain holders of outstanding 1.125% Convertible Senior Notes due 2027; agreed to exchange approximately $56.5 million cash and approximately 188,451 shares of common stock based on the Reference Price for $56.3 million aggregate principal of 2027 Notes; cash/stock amounts subject to adjustment during a 2-day measurement period ending September 14, 2026; closings expected on or about September 16, 2026; cash on hand to fund the exchange; approximately $1.0 million aggregate principal of 2027 Notes expected to remain outstanding immediately following closings; private placement under Securities Act §4(a)(2) offered only to believed QIBs under Rule 144A.

Form 8-K / Ex 99.1 exchange-agreement facts are as of September 10, 2026 (AccNo 0001193125-26-388376); cash and share amounts remain estimates through the measurement period ending September 14, 2026; closings are expected on or about September 16, 2026 and are not stated as closed.

What “Source checked” means

Impinj entered privately negotiated agreements on September 10 to exchange $56.3 million in principal of its 1.125% Convertible Senior Notes due 2027 for an estimated $56.5 million in cash and 188,451 shares of common stock. The Nasdaq-listed company said it will fund the cash portion with cash on hand. The agreements set out an exchange of debt for cash and equity, with the consideration still subject to adjustment before the expected closings.

The distinction between an agreement and a completed transaction matters here. Impinj expects the closings to take place on or about September 16. Immediately after those closings, it expects approximately $1.0 million in aggregate principal of the 2027 notes to remain outstanding. Both statements describe the anticipated outcome; the September 10 announcement does not establish that the exchanges have closed or that the outstanding debt has already been reduced to that level.

The cash and share figures are estimates, too. They are subject to adjustment over a two-day measurement period ending September 14. Impinj said the approximations use an assumed share price equal to the Nasdaq Global Select Market closing price on the agreement date and the Reference Price used in the exchange transactions. Actual cash paid and shares issued could vary with the stock's trading price during the measurement period. The announced consideration therefore is not a final settlement amount.

For investors following Impinj's capital structure, the announcement identifies the principal covered by the agreements, the planned use of existing cash and the stock component of the consideration. It also provides a conditional estimate of the 2027 notes that would remain. The two dates to distinguish are September 14, when the measurement period ends, and approximately September 16, when the company expects the closings. The first concerns the consideration; the second concerns completion of the exchanges.

The exchanges were privately negotiated with certain holders of the outstanding notes. The common shares are to be issued in a private placement under Section 4(a)(2) of the Securities Act and were offered only to persons believed to be qualified institutional buyers under Rule 144A. Impinj disclosed the exchange in an 8-K under Items 8.01 and 9.01, with its September 10 press release attached as Exhibit 99.1. The filing's accession number is 0001193125-26-388376.

Seattle-based Impinj describes itself in the release as a RAIN RFID provider and Internet of Things pioneer. Its company description says its products and solutions identify and track everyday items to connect the physical world with digital systems. That business context is separate from the exchange terms: the financing update centers on the 2027 notes, the provisional cash and stock consideration, and the expected completion timetable.

What this filing does not settle

The Form 8-K / Ex 99.1 does not state that the exchange has closed, does not disclose the Reference Price dollar amount or VWAP, does not give the aggregate principal of 2027 Notes outstanding before the exchange, does not provide final cash or share amounts after the measurement period, and does not disclose dilution percentage, credit ratings, or share-price reaction.
