Moog (MOG) retirement trust holds 18% of Class B shares in new 13D/A

Rhea-AI Filing Summary

Moog Inc.’s Supplemental Retirement Plan Trust filed an amended Schedule 13D reporting beneficial ownership of 826,170 shares of Class B common stock, equal to 18.0% of that class, based on 4,594,174 voting Class B shares outstanding as of January 30, 2026.

The shares are held in a New York trust that funds Moog’s supplemental retirement plan, with John P. McGrath serving as trustee.
