Impinj CEO Chris DiOrio Surrenders Shares for Tax Withholding

What Happened

• Chris DiOrio, Ph.D., CEO of Impinj (PI), had RSUs vest and converted those contingent awards into 3,041 shares (1,224 + 1,817). Of those shares, 1,197 were surrendered to the company to satisfy tax withholding obligations, a disposition valued at $177.20 per share for a total of $212,108. The remaining 1,844 shares from this vesting appear to have been retained.

Key Details

• Transaction date: September 23, 2026 (filed September 24, 2026; filing marked late).
• Conversions/vests: 1,224 and 1,817 RSUs converted to common shares (recorded as derivative exercises, code M) at $0 exercise price.
• Tax withholding: 1,197 shares surrendered to the issuer (code F) at $177.20/share for $212,108.
• Shares retained from this vesting: 3,041 vested − 1,197 surrendered = 1,844 shares retained (this reflects only shares from this vesting; total holdings after the transaction are not provided on the form).
• Notable footnotes: RSUs represent the right to one share each. The vested amounts came from grants on March 23, 2023 (19,580 RSUs; one‑sixteenth vested) and March 23, 2024 (29,075 RSUs; one‑sixteenth vested). The filing is marked late (L).

Context

• This was not an open‑market sale but a routine surrender of shares to cover tax withholding upon RSU vesting (a common, administrative transaction). The RSUs converted to shares and a portion was remitted to the company to satisfy tax liabilities — this does not necessarily indicate a change in the CEO’s market view.
