BOCK WILLIAM G 4

What Happened
William G. Bock, a director of Silicon Laboratories Inc. (SLAB), received a grant of 962 restricted stock units (RSUs) on April 23, 2026. The Form 4 lists the acquisition as 962 shares at $0.00 (common for RSU grants); no cash purchase or sale occurred. These RSUs will convert into one share of common stock per RSU upon vesting.

Context
RSUs are a form of equity compensation that convert to actual shares only upon vesting; they may be forfeited if vesting conditions aren’t met. The $0.00 amount on the Form 4 reflects the award reporting convention—not the economic value, which will equal the market price of SLAB shares when the RSUs vest. Grants to directors are common as compensation and do not by themselves indicate the director is buying or selling stock.
