Rhea-AI Filing Summary

On 07/29/2025 Immunome, Inc. (IMNM) granted President & CEO Clay B. Siegall a stock option for 800,000 common shares at an exercise price of $10.60, expiring 07/28/2035. No shares were bought or sold; the filing reflects only an incentive award.

The option vests over four years: 25% on 07/29/2026 and the remaining 75% in equal monthly installments (1/36) thereafter. Following the grant, Siegall beneficially owns 800,000 derivative securities and retains no change in non-derivative share ownership. The transaction was reported on a single-person Form 4 and was not made under a 10b5-1 plan.

This award strengthens management equity alignment but represents potential dilution if exercised. No other financial metrics, sales, or purchases were disclosed in the filing.

Il 29/07/2025 Immunome, Inc. (IMNM) ha concesso al Presidente e CEO Clay B. Siegall un opzione su azioni per 800.000 azioni ordinarie con un prezzo di esercizio di 10,60 $, con scadenza il 28/07/2035. Non sono state acquistate né vendute azioni; la comunicazione riguarda esclusivamente un premio incentivante.

L'opzione si matura in quattro anni: il 25% il 29/07/2026 e il restante 75% in rate mensili uguali (1/36) successivamente. Dopo la concessione, Siegall detiene beneficiariamente 800.000 titoli derivati e non ha modifiche nella proprietà diretta delle azioni. La transazione è stata riportata in un modulo Form 4 individuale e non è stata effettuata nell'ambito di un piano 10b5-1.

Questo premio rafforza l’allineamento azionario della direzione, ma rappresenta una potenziale diluizione in caso di esercizio. Nessun altro dato finanziario, vendita o acquisto è stato reso noto nel deposito.

Le 29/07/2025, Immunome, Inc. (IMNM) a accordé au Président et CEO Clay B. Siegall une option d'achat portant sur 800 000 actions ordinaires à un prix d'exercice de 10,60 $, expirant le 28/07/2035. Aucune action n'a été achetée ou vendue ; le dépôt reflète uniquement une attribution incitative.

Après l'attribution, Siegall détient bénéficiairement 800 000 titres dérivés et ne modifie pas sa détention directe d'actions. La transaction a été rapportée via un formulaire Form 4 individuel et n'a pas été réalisée dans le cadre d'un plan 10b5-1.

Am 29.07.2025 gewährte Immunome, Inc. (IMNM) dem Präsidenten und CEO Clay B. Siegall eine Aktienoption über 800.000 Stammaktien zu einem Ausübungspreis von 10,60 $, die am 28.07.2035 verfällt. Es wurden keine Aktien gekauft oder verkauft; die Meldung betrifft ausschließlich eine Anreizgewährung.

Die Option wird über vier Jahre vestet: 25 % am 29.07.2026 und die verbleibenden 75 % in gleichen monatlichen Raten (1/36) danach. Nach der Gewährung besitzt Siegall wirtschaftlich 800.000 derivative Wertpapiere und es gibt keine Änderung seines direkten Aktienbesitzes. Die Transaktion wurde in einem Einzelperson-Formular 4 gemeldet und nicht im Rahmen eines 10b5-1-Plans durchgeführt.

Diese Zuwendung stärkt die Interessenangleichung des Managements, stellt aber bei Ausübung eine potenzielle Verwässerung dar. Weitere finanzielle Kennzahlen, Verkäufe oder Käufe wurden in der Meldung nicht offengelegt.

Positive
  • Large option grant ties CEO compensation directly to long-term share price performance, aligning interests with shareholders.
Negative
  • Potential dilution of roughly 2â€�3% of outstanding shares if the 800,000 options are fully exercised.

Insights

TL;DR: Large option grant aligns CEO to value creation; limited immediate impact on float or valuation.

The 800k-share option equals roughly four years of typical executive equity compensation and signals the board’s confidence in Dr. Siegall’s leadership. At a $10.60 strike, incentives are out-of-the-money if shares trade lower, limiting near-term dilution. Investors should factor in potential dilution of ~2.5% of current basic shares if fully exercised, but vesting and a 10-year term spread that effect over time. No insider selling occurred, which is modestly reassuring. Overall impact is neutral to slightly positive.

TL;DR: Grant structure follows best-practice four-year vest; no 10b5-1 plan attached.

The award uses a standard 25% one-year cliff plus monthly vesting thereafter, promoting retention through 2029. Absence of a 10b5-1 designation means sales discretion remains with the insider, which can draw governance scrutiny later. Strike price equals the market close on grant date (implied), mitigating back-dating risk. Board transparency is adequate; impact on governance score is neutral.
