Howe Elizabeth A. 4

What Happened

• Elizabeth A. Howe, CFO of SITIME Corp (SITM), disposed of 2,738 shares on 2026-05-20 at $697.00 per share, a total of $1,908,386. The filing lists the disposition as code F (payment of exercise price or tax liability), meaning the shares were surrendered/withheld to cover tax or exercise obligations rather than sold on the open market.

Key Details

• Transaction date and price: 2026-05-20 at $697.00 per share.
• Shares disposed: 2,738; reported total value: $1,908,386.
• Filing date: 2026-05-22 (filed two days after the transaction) — appears timely.
• Shares owned after transaction: filing does not state a total beneficial ownership figure, but includes footnote details below.
• Footnote: F1 notes an aggregate of 58,148 shares issuable under previously reported equity awards that have not vested (37,466 time-vesting restricted stock units and 20,682 performance-based restricted stock units).

Context

• Code F transactions typically reflect shares surrendered or withheld to satisfy tax withholding or to pay an exercise price; these are administrative actions and do not necessarily signal insider sentiment about the company. This was not an open-market sale. The filing includes unvested RSUs and PSUs that may convert to shares in the future if vesting conditions are met.
