ROGERS MARK N 4

What Happened

• Mark N. Rogers, EVP & General Counsel of Amkor Technology, converted (exercised) a total of 16,112 restricted stock units (RSUs) on February 20, 2026 (entries of 7,422 and 8,690 shares). The RSU conversion was at $0 exercise price (these RSUs were granted for service).
• To cover tax withholding obligations, the company withheld 6,905 shares (3,181 and 3,724 shares) and recorded dispositions at $47.94 per share, generating proceeds of approximately $152,497 and $178,529, respectively—about $331,026 total.
• Net shares received by Rogers after withholding: 9,207 shares (16,112 converted − 6,905 withheld). This was a vesting/conversion event (award-related), not an open-market purchase or voluntary sale.

Key Details

• Transaction date: February 20, 2026; Form 4 filed February 24, 2026 (timely filing).
• Conversion/exercise price: $0 per share (RSUs converted for no cash consideration).
• Withheld share sale price: $47.94 per share; withheld-share proceeds ≈ $331,026.
• Net increase in shares held by Rogers from this event: +9,207 shares.
• Footnotes: Withheld shares satisfy the reporting person’s tax withholding obligations; the issuer pays the taxes on the reporting person’s behalf (see F1, F2). RSUs were from 2024 and 2025 grant dates and vest in three equal annual installments (see F3, F4).
• Filing timing: appears timely (filed within the two-business-day Form 4 window).

Context

• This was a vesting/conversion of RSUs with shares withheld for tax obligations (a common cashless-withholding method), not an open-market sale or purchase that signals trading intent.
• For retail investors, award vesting and employer tax withholding are routine and reflect compensation mechanics rather than a direct insider market view.
