Rhea-AI Filing Summary

Form 4 highlights: On 07/31/2025 Arthur J. Gallagher & Co. (AJG) President Thomas J. Gallagher converted 1,376.035 notional stock units into an equal number of common shares under the company’s Supplemental Savings and Thrift Plan (transaction code M). The units carried a $0 exercise price because they represent previously deferred compensation.

Following the distribution, Gallagher’s direct holdings rise to 308,921.08 shares. He also retains substantial indirect ownership: 62,295 shares in a GRAT, 66,709 in an irrevocable trust, 181,228 held by his wife in various trusts, and 418.7 in a 401(k) plan. In aggregate, his economic exposure exceeds 619 k shares, while 10,233.3409 notional stock units remain outstanding for future settlement (payable in July 2025�26 or upon separation).

No open-market purchase or sale occurred; the conversion simply shifts deferred units into common stock and marginally increases insider equity alignment. The filing does not signal a change in company fundamentals or provide earnings guidance.

Punti salienti del Modulo 4: Il 31/07/2025 Thomas J. Gallagher, Presidente di Arthur J. Gallagher & Co. (AJG), ha convertito 1.376,035 unità azionarie teoriche in un pari numero di azioni ordinarie nell'ambito del Piano Supplementare di Risparmio e Previdenza della società (codice transazione M). Le unità avevano un prezzo di esercizio di 0 $ in quanto rappresentano compensi differiti precedentemente.

Dopo la distribuzione, le partecipazioni dirette di Gallagher salgono a 308.921,08 azioni. Mantiene inoltre una significativa proprietà indiretta: 62.295 azioni in un GRAT, 66.709 in un trust irrevocabile, 181.228 detenute da sua moglie in vari trust e 418,7 in un piano 401(k). Complessivamente, la sua esposizione economica supera le 619.000 azioni, mentre 10.233,3409 unità azionarie teoriche restano in sospeso per future liquidazioni (pagabili tra luglio 2025 e 2026 o al momento della separazione).

Non si è verificato alcun acquisto o vendita sul mercato aperto; la conversione ha semplicemente trasformato unità differite in azioni ordinarie, aumentando marginalmente l'allineamento azionario degli insider. La comunicazione non indica cambiamenti nei fondamentali aziendali né fornisce previsioni sugli utili.

Aspectos destacados del Formulario 4: El 31/07/2025 Thomas J. Gallagher, presidente de Arthur J. Gallagher & Co. (AJG), convirtió 1,376.035 unidades teóricas de acciones en un número igual de acciones comunes bajo el Plan Suplementario de Ahorro y Retiro de la compañía (código de transacción M). Las unidades tenían un precio de ejercicio de $0 porque representan compensación previamente diferida.

Tras la distribución, las participaciones directas de Gallagher aumentan a 308,921.08 acciones. También mantiene una considerable propiedad indirecta: 62,295 acciones en un GRAT, 66,709 en un fideicomiso irrevocable, 181,228 en varios fideicomisos a nombre de su esposa y 418.7 en un plan 401(k). En conjunto, su exposición económica supera las 619 mil acciones, mientras que 10,233.3409 unidades teóricas de acciones permanecen pendientes para liquidación futura (pagaderas en julio de 2025�26 o al momento de la separación).

No se realizó ninguna compra o venta en el mercado abierto; la conversión simplemente transforma unidades diferidas en acciones comunes y aumenta marginalmente la alineación accionarial de los insiders. La presentación no indica cambios en los fundamentos de la empresa ni proporciona orientación sobre ganancias.

Points clés du formulaire 4 : Le 31/07/2025, Thomas J. Gallagher, président d'Arthur J. Gallagher & Co. (AJG), a converti 1 376,035 unités d'actions notionnelles en un nombre égal d'actions ordinaires dans le cadre du Plan d'épargne supplémentaire et d'épargne salariale de la société (code de transaction M). Ces unités avaient un prix d'exercice de 0 $ car elles représentent une rémunération différée antérieurement.

Après la distribution, les participations directes de Gallagher s'élèvent à 308 921,08 actions. Il conserve également une importante propriété indirecte : 62 295 actions dans un GRAT, 66 709 dans une fiducie irrévocable, 181 228 détenues par son épouse dans divers trusts, et 418,7 dans un plan 401(k). Au total, son exposition économique dépasse 619 000 actions, tandis que 10 233,3409 unités d'actions notionnelles restent en suspens pour un règlement futur (payable en juillet 2025�26 ou lors d'une séparation).

Aucun achat ou vente sur le marché ouvert n'a eu lieu ; la conversion se contente de transformer des unités différées en actions ordinaires, augmentant légèrement l'alignement des intérêts des initiés. Le dépôt ne signale aucun changement dans les fondamentaux de l'entreprise ni ne fournit de prévisions de résultats.

Formular 4 Highlights: Am 31.07.2025 wandelte Thomas J. Gallagher, Präsident von Arthur J. Gallagher & Co. (AJG), 1.376,035 nominelle Aktienanteile in eine gleiche Anzahl von Stammaktien im Rahmen des ergänzenden Spar- und Thrift-Plans des Unternehmens um (Transaktionscode M). Die Einheiten hatten einen Ausübungspreis von 0 $, da sie zuvor aufgeschobene Vergütungen darstellen.

Nach der Ausschüttung steigen Gallaghers direkte Beteiligungen auf 308.921,08 Aktien. Er hält zudem beträchtliches indirektes Eigentum: 62.295 Aktien in einem GRAT, 66.709 in einem unwiderruflichen Trust, 181.228, die seine Ehefrau in verschiedenen Trusts hält, und 418,7 in einem 401(k)-Plan. Insgesamt übersteigt seine wirtschaftliche Beteiligung 619.000 Aktien, während 10.233,3409 nominelle Aktienanteile für zukünftige Abrechnungen ausstehen (zahlbar im Juli 2025�26 oder bei Ausscheiden).

Es erfolgte kein Kauf oder Verkauf am offenen Markt; die Umwandlung verschiebt lediglich aufgeschobene Einheiten in Stammaktien und erhöht geringfügig die Insider-Aktienausrichtung. Die Meldung signalisiert keine Änderung der Unternehmensgrundlagen oder gibt Gewinnprognosen ab.

Positive
  • Increased direct ownership: President added 1,376 shares, modestly raising insider equity alignment without reducing indirect holdings.
Negative
  • None.

Insights

TL;DR: Routine deferred-comp unit conversion; no cash outflow, minimal share-count impact, neutral signal.

The 1,376-share increase is immaterial (<0.1 % of AJG’s 208 m share count) and results from scheduled plan distributions, not discretionary trading. Gallagher continues to hold >600 k shares plus 10 k units, indicating long-term alignment. Because no shares were sold and there was no price, liquidity or sentiment effects are negligible. I classify the event as not impactful to valuation or near-term price action.
