Gibson Daniel Patrick 4

What Happened

• Daniel Patrick Gibson, a director of Impinj (PI), had 3,114 restricted stock units (RSUs) convert/vest on May 28, 2026 (reported on Form 4). The filing shows a conversion/exercise event for 3,114 RSU-derived shares and a simultaneous disposition of 3,114 shares (derivative), with a grant/award entry showing 1,896 shares acquired. In effect, 3,114 RSUs vested and 1,896 shares were issued to Gibson while 1,218 shares were withheld/disposed (commonly to satisfy tax withholding).

Key Details

• Transaction date: May 28, 2026; Form 4 filed May 29, 2026 (timely).
• Reported entries: M (exercise/conversion of derivative) 3,114 shares @ $0.00; M (disposition of derivative) 3,114 shares @ $0.00; A (award/grant) 1,896 shares @ $0.00.
• Net shares received by Gibson: 1,896; shares withheld/retired: 1,218 (3,114 − 1,896).
• Footnotes: The 3,114 RSUs were granted June 5, 2025 and vested May 28, 2026 (F3). A separate RSU grant referenced will fully vest May 28, 2027 (F4). F1 notes Gibson’s ownership/roles in Sylebra entities that may give him shared voting/dispositive power over certain institutional holdings; this relates to institutional positions, not an executive open-market trade.
• Shares owned after the transaction: not specified in the provided filing details.

Context

• This was a vesting/net-settlement of RSUs (derivative conversion), not an open-market purchase or sale for cash. The withheld/disposed shares are routine for tax withholding and do not necessarily indicate a change in sentiment. The filing appears timely (filed one day after the transaction date).
