Form 4 – Dorman Products, Inc. (DORM)

SVP & CIO Donna M. Long reported two open-market sales on 28 Jul 2025:

  • 2 common shares at a weighted average price of $121.60
  • 818 common shares at a weighted average price of $122.2108

Aggregate shares sold: 820, for gross proceeds of roughly $100,000. Post-sale direct ownership declines to 19,073.8738 shares, a reduction of about 4 % of her prior position. No derivative securities were exercised or acquired, and no 10b5-1 trading plan is referenced.

The filing is routine and does not indicate any corporate events or financial performance issues. Given the modest size relative to both Long’s remaining stake and Dorman’s ~30 million-share float, the transaction is unlikely to exert meaningful pressure on the stock, but investors may track insider activity as a sentiment gauge.

Modulo 4 – Dorman Products, Inc. (DORM)

La SVP e CIO Donna M. Long ha segnalato due vendite sul mercato aperto il 28 luglio 2025:

  • 2 azioni ordinarie a un prezzo medio ponderato di 121,60 $
  • 818 azioni ordinarie a un prezzo medio ponderato di 122,2108 $

Totale azioni vendute: 820, per un ricavo lordo di circa 100.000 $. Dopo la vendita, la proprietà diretta scende a 19.073,8738 azioni, una riduzione di circa il 4% rispetto alla posizione precedente. Non sono stati esercitati o acquisiti titoli derivati, né è stato fatto riferimento a un piano di trading 10b5-1.

La comunicazione è di routine e non indica eventi societari o problemi di performance finanziaria. Considerando la dimensione modesta rispetto sia alla quota residua di Long che al flottante di circa 30 milioni di azioni di Dorman, la transazione probabilmente non influenzerà significativamente il titolo, ma gli investitori potrebbero monitorare l’attività degli insider come indicatore di sentiment.

Formulario 4 – Dorman Products, Inc. (DORM)

La SVP y CIO Donna M. Long reportó dos ventas en el mercado abierto el 28 de julio de 2025:

  • 2 acciones ordinarias a un precio promedio ponderado de 121,60 $
  • 818 acciones ordinarias a un precio promedio ponderado de 122,2108 $

Acciones totales vendidas: 820, por ingresos brutos aproximados de 100,000 $. Tras la venta, la propiedad directa disminuye a 19,073.8738 acciones, una reducción de alrededor del 4% respecto a su posición previa. No se ejercieron ni adquirieron valores derivados, ni se menciona un plan de trading 10b5-1.

La presentación es rutinaria y no indica eventos corporativos ni problemas de desempeño financiero. Dado el tamaño modesto en relación con la participación restante de Long y el flotante de aproximadamente 30 millones de acciones de Dorman, es poco probable que la transacción ejerza una presión significativa sobre la acción, aunque los inversores podrían seguir la actividad de los insiders como indicador de sentimiento.

양식 4 – 도먼 프로덕츠, Inc. (DORM)

SVP 겸 CIO Donna M. Long이 2025년 7월 28일 두 건의 공개 시장 매도를 보고했습니다:

  • 가중 평균 가격 $121.60에 보통주 2주
  • 가중 평균 가격 $122.2108에 보통주 818주

총 매도 주식 수: 820주, 총 매출액 약 $100,000. 매도 후 직접 보유 주식은 19,073.8738주로 감소하여 이전 보유량의 약 4% 감소했습니다. 파생 증권은 행사하거나 취득하지 않았으며, 10b5-1 거래 계획은 언급되지 않았습니다.

해당 제출은 일상적인 것으로, 기업 이벤트나 재무 성과 문제를 나타내지 않습니다. Long의 잔여 지분 및 약 3천만 주의 Dorman 유동 주식 수에 비해 규모가 작아 이번 거래가 주가에 큰 영향을 미치지 않을 가능성이 높지만, 투자자들은 내부자 활동을 심리 지표로 주시할 수 있습니다.

Formulaire 4 – Dorman Products, Inc. (DORM)

La SVP et CIO Donna M. Long a déclaré deux ventes sur le marché libre le 28 juillet 2025 :

  • 2 actions ordinaires à un prix moyen pondéré de 121,60 $
  • 818 actions ordinaires à un prix moyen pondéré de 122,2108 $

Nombre total d’actions vendues : 820, pour un produit brut d’environ 100 000 $. Après la vente, la détention directe chute à 19 073,8738 actions, soit une réduction d’environ 4 % par rapport à sa position précédente. Aucun titre dérivé n’a été exercé ou acquis, et aucun plan de trading 10b5-1 n’est mentionné.

Le dépôt est de routine et ne signale aucun événement d’entreprise ni problème de performance financière. Étant donné la taille modeste par rapport à la participation restante de Long et au flottant d’environ 30 millions d’actions de Dorman, cette transaction est peu susceptible d’exercer une pression significative sur le cours de l’action, mais les investisseurs peuvent suivre l’activité des initiés comme indicateur de sentiment.

SVP und CIO Donna M. Long meldete am 28. Juli 2025 zwei Verkäufe am offenen Markt:

  • 2 Stammaktien zu einem gewichteten Durchschnittspreis von 121,60 $
  • 818 Stammaktien zu einem gewichteten Durchschnittspreis von 122,2108 $

Insgesamt verkaufte Aktien: 820, mit Bruttoerlösen von etwa 100.000 $. Nach dem Verkauf sinkt ihr Direktbestand auf 19.073,8738 Aktien, eine Verringerung von etwa 4 % gegenüber ihrer vorherigen Position. Es wurden keine Derivate ausgeübt oder erworben, und es wird kein 10b5-1 Handelsplan erwähnt.

Die Meldung ist routinemäßig und weist nicht auf Unternehmensereignisse oder finanzielle Probleme hin. Angesichts der vergleichsweise geringen Größe im Verhältnis zu Longs verbleibendem Anteil und dem etwa 30 Millionen Aktien umfassenden Streubesitz von Dorman ist es unwahrscheinlich, dass die Transaktion den Aktienkurs wesentlich beeinflusst, doch Anleger könnten die Insideraktivität als Stimmungsindikator beobachten.

Insights

TL;DR: Small insider sale; negligible impact.

The 820-share sale (~$100k) represents only 4 % of Ms. Long’s holdings and an immaterial fraction of DORM’s float. No options exercised, no sign of strategic shift. Such routine diversification sales typically carry neutral informational value unless part of a larger pattern. I view the impact on valuation or near-term trading as minimal.

TL;DR: Governance clean; filing timely and standard.

The Form 4 is timely (filed next day), includes weighted-average footnotes, and shows no ambiguous indirect holdings. Absence of derivative activity or accelerated selling suggests compliance rather than opportunism. I classify the disclosure as not impactful for governance risk.
