Shi Parker 4

What Happened

• Shi Parker, COO of East West Bancorp (EWBC), received 16,538 shares on March 1, 2026 upon vesting of performance-based restricted stock units (RSUs). The award is reported as an acquisition (code A).
• To satisfy tax withholding (code F), 6,857 of those shares were withheld at $109.45 per share (based on the Feb 27, 2026 close) for a tax payment of $750,499. Net shares added to Parker's holdings = 9,681 shares (16,538 granted minus 6,857 withheld), with an estimated gross value of the vested award of roughly $1.81M and net value retained of about $1.06M (both estimated using $109.45).

Key Details

• Transaction date: March 1, 2026; Filing date: March 3, 2026 (filed within the two-business-day Form 4 window).
• Award (A): 16,538 shares acquired via vesting of performance-based RSUs originally granted March 1, 2023.
• Tax withholding (F): 6,857 shares withheld at $109.45/share = $750,499 paid to cover tax liability.
• Shares owned after transaction: not disclosed in this filing.
• Footnotes: F1 — These were performance-based RSUs granted 3/1/2023; 179.1% of the original grant was earned and vested. F2 — Because 3/1/2026 was a Sunday, withholding used the issuer's 2/27/2026 closing price.

Context

• This was a vesting/settlement of performance RSUs, not an open-market sale or purchase. Withholding shares to cover taxes is a routine, administrative event and is coded F on Form 4.
• The unusually high payout (179.1% of the original grant) reflects above-target performance metrics for that award cycle; it increases the executive’s holdings net of withholding.
