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.

The earlier Form 4 had shown 129,302 shares withheld due to a clerical error in the calculation. After this correction, Miosi directly beneficially owns 601,882.361 shares of MGIC Investment Corp common stock. The event reflects routine payroll tax handling rather than an open-market sale.
