Key Details

• Filing: Form 8‑K (Item 5.02) disclosing officer departure and appointment.
• CFO departure: Jason Secore — employment ends September 29, 2026.
• Appointment: Andreas Raptopoulos (current CEO) named CFO effective September 29, 2026; will serve as principal financial and accounting officer in addition to CEO duties.
• Company initiated search for a permanent CFO; biographical info for Mr. Raptopoulos previously provided in the May 29, 2026 8‑K.

Why It Matters A change in the principal financial officer is a material leadership event investors typically watch because the CFO oversees financial reporting and controls. Matternet’s CEO temporarily taking on CFO responsibilities centralizes executive control and may affect near‑term management bandwidth; investors should monitor future filings for appointment of a permanent CFO, any disclosure about delegation of accounting responsibilities, and potential updates to financial reporting or internal control disclosures.
