Insights

Corporate Insider

Majority of a 2021 award vested; 303 shares were withheld for taxes.

What it means: The report documents routine vesting of an equity award granted on 10/01/2021, where 692 shares vested and the company withheld 303 shares to cover tax obligations.

Why it matters: This is a standard withholding-driven disposition rather than an active open-market sale, and the reporting person still retains significant direct ownership of 13,427 shares plus 67 401(k) share equivalents, while 10,138 shares remain under restriction with defined lapse dates through 06/05/2028.
