Rhea-AI Filing Summary

Impinj, Inc. director and Chief Executive Officer received a grant of 15,015 restricted stock units (RSUs), each representing a contingent right to one share of common stock. The award vests over time: one-quarter of the shares vest after one year, with the remaining shares vesting in equal quarterly installments of one-sixteenth each thereafter, subject to continued service. The reported transaction shows the RSUs were granted at a $0 exercise price and are held directly by the reporting person. The grant appears to be standard equity compensation tied to ongoing service and future vesting.

Impinj, Inc. il direttore e Amministratore Delegato ha ricevuto una concessione di 15.015 unità azionarie vincolate (RSU), ciascuna corrispondente al diritto condizionato a una azione ordinaria. L’assegnazione matura nel tempo: un quarto delle azioni matura dopo un anno, mentre le restanti azioni maturano in rate trimestrali uguali, corrispondenti ciascuna a un sedicesimo, subordinatamente alla continuazione del rapporto. La transazione riportata indica che le RSU sono state assegnate con prezzo di esercizio pari a $0 e sono detenute direttamente dalla persona che effettua la segnalazione. La concessione sembra essere una tipica remunerazione azionaria legata al servizio continuativo e al vesting futuro.

La transacción informada muestra que las RSU se otorgaron con precio de ejercicio de $0 y están en posesión directa de la persona informante. La adjudicación parece ser una compensación estándar en acciones vinculada al servicio continuado y al vesting futuro.

L’attribution acquiert des droits progressivement : un quart des actions acquiert après un an, les actions restantes s’acquièrent ensuite par trimestres égaux, chacun correspondant à un seizième, sous réserve de la poursuite du service. La transaction déclarée indique que les RSU ont été attribuées avec un prix d’exercice de 0 $ et sont détenues directement par la personne déclarante. L’attribution semble constituer une rémunération en actions standard liée au maintien du poste et au vesting futur.

Impinj, Inc. der Direktor und Chief Executive Officer erhielt eine Zuteilung von 15.015 Restricted Stock Units (RSUs), von denen jede ein bedingtes Recht auf eine Stammaktie darstellt. Die Zuteilung erfolgt gestaffelt: ein Viertel der Aktien wird nach einem Jahr fällig, die verbleibenden Aktien werden anschließend in gleichen vierteljährlichen Raten zu jeweils einem Sechzehntel freigegeben, vorbehaltlich fortgesetzter Tätigkeit. Die gemeldete Transaktion weist aus, dass die RSUs zu einem Ausübungspreis von $0 gewährt wurden und vom meldenden Personen direkt gehalten werden. Die Zuteilung scheint eine übliche aktienbasierte Vergütung zu sein, die an fortlaufende Dienstzeit und künftiges Vesting gekoppelt ist.

Positive
  • Time‑based vesting aligns CEO incentives by requiring continued service before shares vest

Insights

TL;DR: CEO received a time‑based RSU grant of 15,015 shares with multi-year vesting, aligning pay with continued service.

The grant of 15,015 RSUs to the CEO is a common governance practice to align executive incentives with shareholder outcomes by tying value realization to continued service and share price performance. The vesting schedule—25% after one year and then quarterly vesting thereafter—promotes retention. The grant price noted as $0 reflects the nature of RSUs (not options) and that shares are delivered upon vesting rather than exercised.

TL;DR: This is a routine, time‑vested RSU award; the absolute size (15,015 RSUs) should be evaluated against total outstanding shares for materiality.

The RSU award structure—contingent receipt of common stock with defined vesting—follows standard executive compensation design. Key facts: 15,015 RSUs, one‑quarter vesting after one year, then 1/16th quarterly. The filing does not disclose grant date fair value, total outstanding shares, or whether any performance conditions apply, limiting assessment of dilution or pay‑for‑performance alignment.
