Howe Elizabeth A. 4

What Happened

• Elizabeth A. Howe, CFO of SITIME Corp (SITM), received four awards on Feb 10, 2026 totaling 15,621 restricted and performance-based stock units (RSUs/PRSUs). These were granted at $0.00 per share (no cash purchase).
• The awards are subject to time-based vesting and/or performance conditions and therefore do not represent an open-market purchase or sale.

Key Details

• Transaction date: February 10, 2026; reported on Form 4 filed February 12, 2026 (timely). Transaction code: A (award/grant).
• Grants (total = 15,621 shares): 1,806; 5,629; 4,093; 4,093 — all at $0.00 acquisition price.
• Notable footnotes from the filing:
  • F1: RSU award under Executive Bonus & Retention Plan — vest 50% on May 20, 2026 and 50% on Aug 20, 2026.
  • F2: Additional shares tied to performance for PRSUs (relates to a 11,258-share PRSU award) — vesting date Feb 20, 2027 if performance met.
  • F3: RSU award vesting 6.25% on Feb 20, 2026 and quarterly thereafter.
  • F4: PRSUs are contingent rights to receive one share per unit and vest based on relative total stockholder return over a three‑year performance period.
  • F5: Filing notes an aggregate of 68,000 shares issuable under previously reported unvested RSUs/PRSUs (47,318 time‑based RSUs; 20,682 PRSUs).
• Shares owned/issuable after this filing include those unvested units noted in F5 (see above).

Context

• RSUs are time‑based awards that convert into shares as they vest; PRSUs only convert if performance targets are met. These awards are compensation/retention tools rather than open‑market insider buys or sales.
• Because these are grants (not purchases or sales), they should be viewed as part of executive pay and retention; they do not by themselves indicate immediate buying or selling activity.
