MGIC Investment (NYSE: MTG) COO updates Form 4 tax-withheld shares

Rhea-AI Filing Summary

MGIC Investment Corp President & COO Salvatore A. Miosi filed an amended Form 4 to correct a prior tax withholding entry tied to share vesting on March 2, 2026. The amendment reports that 129,321 shares of Common Stock were disposed of to satisfy tax withholding obligations, a non-market transaction classified as a tax-withholding disposition.
