Insights

Equity Compensation Analyst

Routine RSU grant increases CEO’s equity stake over three-year vesting.

The CEO of SkyWater Technology, Thomas Sonderman, was granted 50,455 RSUs at no cash cost, vesting ratably over three years. This is characterized as a grant or award, a standard equity compensation mechanism rather than an open-market purchase.

The award raises his direct holdings to 566,445 common shares, aligning part of his compensation with shareholder outcomes over time. Because the RSUs vest only if he remains in service on each anniversary, they also act as a retention tool. The filing does not show any derivative positions, suggesting this report focuses solely on the new RSU award.
