What Happened
Robert M. Johnson, President, CEO and a director of Silicon Laboratories, reported two dispositions totaling 18,387 shares worth about $3.98 million. On 2026-05-15, 10,363 shares were withheld to satisfy taxes on a previously reported equity award (10,363 shares at $216.59; ~$2.244M). On 2026-05-18, he sold 8,024 shares in an open-market transaction (8,024 shares at $216.83; ~$1.740M). Both transactions are dispositions (F = tax withholding; S = open-market sale).

Context

• Tax-withholding dispositions are common when restricted stock or RSUs vest — the company withholds shares to cover required taxes and those withheld shares are reported as disposed (code F). These do not necessarily reflect a voluntary decision to sell additional shares.
• The 8,024-share transaction on 2026-05-18 was an open-market sale (code S), which is a standard disposition type; Form 4s record these for transparency but do not by themselves indicate the insider’s longer-term view.
