Rhea-AI Filing Summary

Form 4 overview: Rhythm Pharmaceuticals (RYTM) disclosed that director Stuart A. Arbuckle received new equity awards on 24 June 2025.

The filing records the grant of 7,037 stock options with a $63.66 exercise price, expiring 23 June 2035, and 4,712 restricted stock units (RSUs). Both awards fully vest on the earlier of 24 June 2026 or the day immediately before the 2026 annual stockholder meeting, provided the director remains on the board. No non-derivative common-stock transactions were reported, and the director now beneficially owns the full amount of these derivative securities.

This appears to be routine annual board compensation that aligns the director’s incentives with shareholders and carries minimal dilution, offering little direct impact on Rhythm’s near-term financial outlook.

Panoramica del Modulo 4: Rhythm Pharmaceuticals (RYTM) ha comunicato che il direttore Stuart A. Arbuckle ha ricevuto nuovi premi azionari il 24 giugno 2025.

La documentazione riporta l’assegnazione di 7.037 opzioni su azioni con un prezzo di esercizio di 63,66 dollari, con scadenza il 23 giugno 2035, e 4.712 unità azionarie vincolate (RSU). Entrambi i premi maturano completamente alla data precedente al 24 giugno 2026 o al giorno immediatamente precedente l’assemblea annuale degli azionisti del 2026, a condizione che il direttore rimanga nel consiglio. Non sono state segnalate transazioni di azioni ordinarie non derivate e il direttore detiene ora la piena proprietà beneficiaria di questi titoli derivati.

Si tratta probabilmente di una normale compensazione annuale del consiglio che allinea gli incentivi del direttore con quelli degli azionisti e comporta una diluizione minima, con scarso impatto diretto sulle prospettive finanziarie a breve termine di Rhythm.

Resumen del Formulario 4: Rhythm Pharmaceuticals (RYTM) informó que el director Stuart A. Arbuckle recibió nuevas concesiones de acciones el 24 de junio de 2025.

El documento registra la entrega de 7,037 opciones sobre acciones con un precio de ejercicio de 63.66 dólares, que vencen el 23 de junio de 2035, y 4,712 unidades restringidas de acciones (RSU). Ambos premios se consolidan completamente en la fecha anterior al 24 de junio de 2026 o al día previo a la junta anual de accionistas de 2026, siempre que el director continúe en el consejo. No se reportaron transacciones de acciones ordinarias no derivadas y el director ahora posee beneficiosamente la totalidad de estos valores derivados.

Esto parece ser una compensación anual rutinaria del consejo que alinea los incentivos del director con los de los accionistas y conlleva una dilución mínima, ofreciendo poco impacto directo en las perspectivas financieras a corto plazo de Rhythm.

양식 4 개요: Rhythm Pharmaceuticals(RYTM)는 이사 Stuart A. Arbuckle가 2025년 6월 24일에 새로운 주식 보상을 받았다고 공시했습니다.

공시 내용에는 행사가격이 63.66달러인 7,037주의 스톡옵션과 4,712주의 제한 주식 단위(RSU)가 포함되어 있으며, 만료일은 2035년 6월 23일입니다. 두 보상 모두 이사가 이사회에 남아 있는 조건 하에 2026년 6월 24일 이전 또는 2026년 연례 주주총회 전날 중 빠른 날에 전액 완전히 취득됩니다. 비파생 보통주 거래는 보고되지 않았으며, 이사는 현재 이 파생 증권 전체를 실질적으로 소유하고 있습니다.

이는 이사의 인센티브를 주주와 일치시키고 희석 효과가 최소화된 일상적인 연간 이사회 보상으로 보이며, Rhythm의 단기 재무 전망에 미치는 직접적인 영향은 거의 없습니다.

Résumé du formulaire 4 : Rhythm Pharmaceuticals (RYTM) a révélé que le directeur Stuart A. Arbuckle a reçu de nouvelles attributions d’actions le 24 juin 2025.

Le dépôt enregistre l’octroi de 7 037 options d’achat d’actions au prix d’exercice de 63,66 dollars, expirant le 23 juin 2035, ainsi que 4 712 unités d’actions restreintes (RSU). Les deux attributions deviennent pleinement acquises à la date la plus proche entre le 24 juin 2026 ou la veille de l’assemblée générale annuelle des actionnaires de 2026, à condition que le directeur reste au conseil d’administration. Aucune transaction d’actions ordinaires non dérivées n’a été signalée, et le directeur détient désormais la pleine propriété bénéficiaire de ces titres dérivés.

Il semble s’agir d’une rémunération annuelle courante du conseil d’administration qui aligne les incitations du directeur avec celles des actionnaires et entraîne une dilution minimale, offrant peu d’impact direct sur les perspectives financières à court terme de Rhythm.

Überblick Formular 4: Rhythm Pharmaceuticals (RYTM) gab bekannt, dass Direktor Stuart A. Arbuckle am 24. Juni 2025 neue Aktienzuteilungen erhalten hat.

Die Einreichung verzeichnet die Gewährung von 7.037 Aktienoptionen mit einem Ausübungspreis von 63,66 USD, die am 23. Juni 2035 verfallen, sowie 4.712 Restricted Stock Units (RSUs). Beide Zuteilungen werden vollständig am früheren der beiden Termine fällig: dem 24. Juni 2026 oder dem Tag vor der jährlichen Hauptversammlung 2026, vorausgesetzt, der Direktor bleibt im Vorstand. Es wurden keine nicht-derivativen Stammaktientransaktionen gemeldet, und der Direktor besitzt nun wirtschaftlich die volle Menge dieser derivativen Wertpapiere.

Dies scheint eine routinemäßige jährliche Vorstandsvergütung zu sein, die die Anreize des Direktors mit denen der Aktionäre in Einklang bringt und eine minimale Verwässerung mit sich bringt, wodurch sich kaum direkte Auswirkungen auf die kurzfristigen finanziellen Aussichten von Rhythm ergeben.

Positive
  • No insider selling; the director only received equity, indicating continued commitment.
  • Long-term incentives via options expiring in 2035 and RSUs align board and shareholder interests.
Negative
  • Minor dilution from 11,749 additional shares underlying the awards, though likely immaterial.

Insights

TL;DR: Routine equity grant; neutral governance signal.

The Form 4 shows a standard annual equity award to a non-employee director. The absence of any disposals suggests no bearish insider view. The 10-year options at $63.66 and single-year cliff-vesting encourage long-term alignment without over-leveraging dilution risk; underlying shares total 11,749, an immaterial amount in most capital structures. Overall, the filing is informational rather than directional and should not materially influence valuation or risk assessments.
