Martin Gregory Scott 4/A

What Happened
Martin Gregory Scott, a director of Ionetix Corp., was granted and received multiple equity instruments on April 9, 2026 in connection with the closing of Ionetix’s merger.

Most grants were the product of converting Legacy Ionetix securities and option/warrant awards into Issuer securities per the Merger Agreement; one small derivative line (193 shares) shows an exercise price of $0.00.

Context
These transactions are primarily conversion and assumption of Legacy Ionetix equity, options and warrants into the public Issuer’s securities as part of the merger—this is an administrative transfer rather than an open‑market purchase or sale. Several items are derivatives (options/warrants) with different vesting terms; some are fully vested/exercisable while others continue to vest monthly. The reporting person’s beneficial ownership of the Shamrock‑held shares is limited to his pecuniary interest (per the footnote). This amended Form 4 corrects or supplements the original report and was filed after the transaction date.
