Whitestone REIT (WSR) – Form 4 insider filing dated 07/02/2025

Chief Operating Officer Christine J. Mastandrea reported two transactions executed on 06/30/2025:

  • Grant of 23,323 restricted common share units (transaction code A). The award was made at $0 cost under the 2018 Long-Term Equity Incentive Ownership Plan.
  • Withholding of 6,470 common shares (transaction code F) to cover associated tax obligations, valued by the company at $12.48 per share.

After these transactions, Mastandrea’s direct beneficial ownership stands at 410,931 common shares, implying a net increase of 16,853 shares (+4.3%) versus her pre-transaction position.

No derivative securities were reported. Because the acquisition stemmed from an incentive award—not an open-market purchase—the signal is generally regarded as moderately positive; it increases insider alignment but does not reflect discretionary cash outlay. The tax-related share surrender is mechanically neutral.

Whitestone REIT (WSR) – Comunicazione interna Form 4 datata 02/07/2025

La Chief Operating Officer Christine J. Mastandrea ha riportato due operazioni effettuate il 30/06/2025:

  • Assegnazione di 23.323 unità azionarie comuni vincolate (codice transazione A). Il premio è stato concesso a costo zero nell'ambito del Piano di Incentivazione Azionaria a Lungo Termine 2018.
  • Ritenuta di 6.470 azioni ordinarie (codice transazione F) per coprire le imposte dovute, valutate dall'azienda a 12,48 $ per azione.

Dopo queste operazioni, la posizione diretta di proprietà effettiva di Mastandrea ammonta a 410.931 azioni ordinarie, con un incremento netto di 16.853 azioni (+4,3%) rispetto alla posizione precedente.

Non sono stati segnalati titoli derivati. Poiché l’acquisizione deriva da un premio incentivante e non da un acquisto sul mercato aperto, il segnale è generalmente considerato moderatamente positivo; aumenta l’allineamento degli insider ma non implica un esborso di liquidità discrezionale. La cessione di azioni per motivi fiscali è neutra dal punto di vista meccanico.

La Directora de Operaciones Christine J. Mastandrea informó sobre dos transacciones realizadas el 30/06/2025:

  • Concesión de 23.323 unidades restringidas de acciones comunes (código de transacción A). La adjudicación se realizó a costo cero bajo el Plan de Incentivos de Propiedad Accionaria a Largo Plazo 2018.
  • Retención de 6.470 acciones comunes (código de transacción F) para cubrir obligaciones fiscales asociadas, valoradas por la empresa en 12,48 $ por acción.

Después de estas transacciones, la propiedad directa beneficiosa de Mastandrea es de 410.931 acciones comunes, lo que implica un aumento neto de 16.853 acciones (+4,3%) respecto a su posición previa.

No se reportaron valores derivados. Dado que la adquisición provino de un premio incentivado y no de una compra en el mercado abierto, la señal se considera generalmente moderadamente positiva; incrementa la alineación interna pero no refleja un desembolso discrecional de efectivo. La entrega de acciones por motivos fiscales es neutra mecánicamente.

Whitestone REIT (WSR) – 2025년 7월 2일자 내부자 보고서 Form 4

최고운영책임자(COO) Christine J. Mastandrea가 2025년 6월 30일에 실행한 두 건의 거래를 보고했습니다:

  • 23,323주의 제한된 보통주 단위 부여 (거래 코드 A). 이 보상은 2018년 장기 주식 인센티브 소유 계획에 따라 무상으로 이루어졌습니다.
  • 관련 세금 납부를 위한 6,470주의 보통주 원천징수 (거래 코드 F), 회사는 주당 12.48달러로 평가했습니다.

이 거래 후 Mastandrea의 직접적 실질 소유권410,931주로, 거래 전보다 순증가 16,853주(+4.3%)를 나타냅니다.

파생 증권은 보고되지 않았습니다. 인센티브 보상에서 발생한 취득으로서, 공개 시장 매입이 아니기 때문에 이 신호는 일반적으로 중간 정도로 긍정적으로 간주됩니다; 내부자와의 이해관계 일치를 높이지만 임의 현금 지출을 반영하지는 않습니다. 세금 관련 주식 포기는 기계적으로 중립적입니다.

Whitestone REIT (WSR) – Déclaration d’initié Formulaire 4 datée du 02/07/2025

La Directrice des opérations Christine J. Mastandrea a rapporté deux transactions effectuées le 30/06/2025 :

  • Attribution de 23 323 unités d’actions ordinaires restreintes (code transaction A). Cette attribution a été réalisée à coût nul dans le cadre du Plan d’Incitations à Long Terme 2018.
  • Retenue de 6 470 actions ordinaires (code transaction F) pour couvrir les obligations fiscales associées, évaluées par la société à 12,48 $ par action.

Après ces transactions, la détention directe bénéficiaire de Mastandrea s’élève à 410 931 actions ordinaires, ce qui représente une augmentation nette de 16 853 actions (+4,3 %) par rapport à sa position précédente.

Aucun titre dérivé n’a été déclaré. Comme l’acquisition provient d’une attribution incitative et non d’un achat sur le marché ouvert, ce signal est généralement considéré comme modérément positif ; il renforce l’alignement des initiés mais ne traduit pas une dépense discrétionnaire en espèces. La cession d’actions liée à la fiscalité est mécaniquement neutre.

Whitestone REIT (WSR) – Insider-Meldung Form 4 vom 02.07.2025

Chief Operating Officer Christine J. Mastandrea meldete zwei Transaktionen, die am 30.06.2025 durchgeführt wurden:

  • Gewährung von 23.323 eingeschränkten Stammaktieneinheiten (Transaktionscode A). Die Zuteilung erfolgte kostenfrei im Rahmen des 2018 Long-Term Equity Incentive Ownership Plans.
  • Einbehaltung von 6.470 Stammaktien (Transaktionscode F) zur Deckung der damit verbundenen Steuerverpflichtungen, vom Unternehmen mit 12,48 $ pro Aktie bewertet.

Nach diesen Transaktionen beträgt Mastandreas direkter wirtschaftlicher Eigentumsanteil 410.931 Stammaktien, was eine netto Erhöhung um 16.853 Aktien (+4,3 %) gegenüber der vorherigen Position bedeutet.

Es wurden keine Derivate gemeldet. Da der Erwerb aus einer Incentive-Zuteilung und nicht aus einem Kauf am freien Markt resultiert, wird das Signal allgemein als mäßig positiv bewertet; es erhöht die Insider-Ausrichtung, spiegelt jedoch keinen diskretionären Geldaufwand wider. Die steuerbedingte Aktienabgabe ist mechanisch neutral.

Positive
  • Net increase of 16,853 shares in COO's direct ownership, reinforcing management alignment with shareholders.
  • Large absolute holding of 410,931 shares underscores meaningful insider stake.
Negative
  • Share acquisition was an automatic RSU grant, offering weaker bullish signal than an open-market purchase.

Insights

TL;DR: COO received 23k RSUs, net +16.9k shares; ownership up 4%, neutral-to-slightly positive signal.

The filing shows an automatic equity grant rather than an open-market buy, limiting its informational value. However, the resulting 410,931-share stake (≈1% of outstanding if float ~41 M) evidences sizeable insider alignment. The tax-withholding sale at $12.48 is routine and does not suggest bearish sentiment. Overall impact on valuation or liquidity is negligible but directionally constructive for governance optics.
