MADDOCK ERNEST E 4

What Happened

• Ernest E. Maddock, a director of Ultra Clean Holdings, was granted 2,575 restricted stock units (RSUs) on May 22, 2026. The Form 4 reports the acquisition price as $0.00 (code A – award/grant). This is a compensation award rather than a market purchase or sale.

Key Details

• Transaction date: 2026-05-22; filing date: 2026-05-27 (filed 5 days after the transaction).
• Transaction type/code: Award/Grant (A); 2,575 RSUs granted at $0.00 reported price.
• Shares owned after transaction: not specified in the provided filing summary.
• Footnote: RSUs vest 100% on the earlier of the day before the next annual stockholder meeting or one year from the grant date (per footnote F1).
• Timeliness: The Form 4 was filed five days after the reported transaction (insiders are generally required to file within two business days), so the filing appears later than the typical reporting window.

Context

• RSUs are compensation awards that convert to actual shares only if vesting conditions are met; until vested they may be forfeitable and do not represent immediately tradable shares.
• Grants to directors are common as part of compensation plans and do not by themselves indicate buying or selling sentiment in the open market.
