MTSI Director Susan Ocampo Donates Shares; Ownership Largely Unchanged

Rhea-AI Filing Summary

MACOM Technology Solutions (NASDAQ:MTSI) filed a Form 4 reporting that Director and 10% owner Susan Ocampo made a gift of 200,000 common shares on June 24 2025 to a charitable donor-advised fund at a stated price of $0, indicating no pecuniary interest was retained.

After the transfer, Ocampo still beneficially owns 10,235,575 shares indirectly—4,615,331 through the Ocampo Family Trust, 4,118,621 via six trusts for her children, and 1,500,000 through a GRAT—plus 1,623 shares directly. No open-market sales, purchases, or Rule 10b5-1 trading plans were disclosed.

The transaction reduces her total holdings by roughly 2% and appears to be a routine philanthropic move rather than a signal of changed investment or control intentions.
