Cardiff Oncology, Inc. (CRDF) – Form 4 filing dated 06/30/2025

The filing discloses that director Rodney S. Markin received 40,565 stock options on 06/26/2025 at an exercise price of $3.16 per share. The options become exercisable on 06/26/2026 and expire on 06/26/2035. The transaction is coded “A,” indicating an award or grant with no cash paid by the insider. Following the grant, Markin holds 222,865 derivative securities (stock options) directly. No open-market purchases or sales of common stock were reported, and no changes were recorded in Markin’s non-derivative share ownership.

The grant is a routine equity incentive intended to align the director’s interests with those of shareholders. Given the modest size relative to Cardiff Oncology’s total shares outstanding, the transaction is considered immaterial from a dilution standpoint and does not, by itself, signal any change to the company’s strategic outlook or financial condition.

Cardiff Oncology, Inc. (CRDF) – Comunicazione Form 4 del 30/06/2025

La comunicazione rivela che il direttore Rodney S. Markin ha ricevuto 40.565 opzioni su azioni il 26/06/2025, con un prezzo di esercizio di 3,16 $ per azione. Le opzioni potranno essere esercitate a partire dal 26/06/2026 e scadranno il 26/06/2035. La transazione è contrassegnata con il codice “A”, che indica un premio o una concessione senza pagamento in contanti da parte dell’insider. Dopo la concessione, Markin detiene direttamente 222.865 titoli derivati (opzioni su azioni). Non sono stati segnalati acquisti o vendite sul mercato aperto di azioni ordinarie, né variazioni nella proprietà diretta di azioni non derivate di Markin.

La concessione rappresenta un incentivo azionario di routine volto ad allineare gli interessi del direttore con quelli degli azionisti. Considerata la dimensione modesta rispetto al totale delle azioni in circolazione di Cardiff Oncology, l’operazione è ritenuta irrilevante dal punto di vista della diluizione e non indica, di per sé, alcuna modifica nella strategia aziendale o nella situazione finanziaria della società.

La presentación revela que el director Rodney S. Markin recibió 40,565 opciones sobre acciones el 26/06/2025, con un precio de ejercicio de $3.16 por acción. Las opciones podrán ejercerse a partir del 26/06/2026 y expiran el 26/06/2035. La transacción está codificada como “A”, lo que indica una concesión o premio sin pago en efectivo por parte del insider. Tras la concesión, Markin posee directamente 222,865 valores derivados (opciones sobre acciones). No se reportaron compras ni ventas en el mercado abierto de acciones ordinarias, ni cambios en la propiedad directa de acciones no derivadas de Markin.

La concesión es un incentivo de capital rutinario destinado a alinear los intereses del director con los de los accionistas. Dado el tamaño modesto en relación con el total de acciones en circulación de Cardiff Oncology, la transacción se considera insignificante desde el punto de vista de la dilución y no indica por sí sola ningún cambio en la estrategia o situación financiera de la empresa.

Cardiff Oncology, Inc. (CRDF) – 2025년 6월 30일자 Form 4 제출

해당 제출서류에 따르면 이사 Rodney S. Markin은 2025년 6월 26일에 주당 $3.16의 행사 가격으로 40,565주 스톡 옵션을 받았습니다. 이 옵션은 2026년 6월 26일부터 행사 가능하며 2035년 6월 26일에 만료됩니다. 거래 코드는 “A”로, 내부자가 현금을 지불하지 않고 수여받은 보상을 의미합니다. 수여 후 Markin은 직접 222,865개의 파생 증권(스톡 옵션)을 보유하고 있습니다. 보통주 공개 시장에서의 매수 또는 매도 내역은 없으며, Markin의 비파생 주식 보유에도 변화가 없습니다.

이번 수여는 이사의 이해관계를 주주들과 일치시키기 위한 일상적인 주식 인센티브입니다. Cardiff Oncology의 총 발행 주식수에 비해 규모가 작아, 이번 거래는 희석 측면에서 중요하지 않은 것으로 간주되며, 회사의 전략적 전망이나 재무 상태에 단독으로 변화를 시사하지 않습니다.

Cardiff Oncology, Inc. (CRDF) – Déclaration Formulaire 4 datée du 30/06/2025

La déclaration révèle que le directeur Rodney S. Markin a reçu 40 565 options d’achat d’actions le 26/06/2025, au prix d’exercice de 3,16 $ par action. Ces options deviennent exerçables à partir du 26/06/2026 et expirent le 26/06/2035. La transaction est codée « A », indiquant une attribution sans paiement en espèces de la part de l’initié. Après cette attribution, Markin détient directement 222 865 titres dérivés (options d’achat). Aucun achat ou vente d’actions ordinaires sur le marché ouvert n’a été signalé, et aucun changement n’a été enregistré dans la détention d’actions non dérivées de Markin.

Cette attribution constitue une incitation en actions habituelle visant à aligner les intérêts du directeur avec ceux des actionnaires. Étant donné la taille modeste par rapport au nombre total d’actions en circulation de Cardiff Oncology, la transaction est considérée comme non significative du point de vue de la dilution et ne signale pas à elle seule de changement dans la stratégie ou la situation financière de l’entreprise.

Cardiff Oncology, Inc. (CRDF) – Form 4 Einreichung vom 30.06.2025

Die Einreichung zeigt, dass Direktor Rodney S. Markin am 26.06.2025 40.565 Aktienoptionen zu einem Ausübungspreis von 3,16 $ pro Aktie erhalten hat. Die Optionen werden ab dem 26.06.2026 ausübbar und verfallen am 26.06.2035. Die Transaktion ist mit dem Code „A“ gekennzeichnet, was eine Zuteilung oder Gewährung ohne Barzahlung durch den Insider bedeutet. Nach der Zuteilung hält Markin direkt 222.865 derivative Wertpapiere (Aktienoptionen). Es wurden keine Käufe oder Verkäufe von Stammaktien am offenen Markt gemeldet, und es gab keine Änderungen im nicht-derivativen Aktienbesitz von Markin.

Die Zuteilung ist eine routinemäßige Aktienanreizmaßnahme, die darauf abzielt, die Interessen des Direktors mit denen der Aktionäre in Einklang zu bringen. Aufgrund der vergleichsweise geringen Größe im Verhältnis zu den insgesamt ausstehenden Aktien von Cardiff Oncology gilt die Transaktion als aus Verwässerungssicht unerheblich und deutet für sich genommen nicht auf eine Änderung der strategischen Ausrichtung oder der finanziellen Lage des Unternehmens hin.

Insights

TL;DR: Routine option grant; no immediate market impact or signal on fundamentals.

The award of 40,565 options at $3.16 to a board member is standard governance practice. It marginally increases potential dilution but remains negligible versus the company’s fully diluted share count. No share purchases or sales occurred, so there is no directional sentiment to infer. The strike price sits near recent trading ranges, suggesting the grant aligns future upside with shareholder value creation.

TL;DR: Governance-aligned incentive; neutral impact on ownership structure.

The one-year vesting and ten-year term match common small-cap biotech board compensation norms. The filing confirms continued compliance with Section 16 reporting requirements and shows transparent disclosure. Because the grant represents a fraction of 1% of outstanding shares, dilution risk is minimal, and the move neither strengthens nor weakens governance positions materially.
