Securities Analyst

TL;DR: Transaction is a non‑compensatory donation of sponsor shares; the filing updates beneficial ownership counts.

The filing specifies the transfer date (08/27/2025) and that 100,000 Class B shares were transferred for no consideration. It also confirms the conversion mechanics (Class B to Class A) and that the Sponsor's holdings are beneficially owned by Dr. Dinu and Dr. Katz through GigAcquisitions7 Corp., with both having voting and dispositive power. The disclosure is factual and clarifies post‑transaction beneficial ownership of 10,107,246 Class A shares.
